Botanical name: Grevillea.
Grevillea plant - family. Proteus.
Origin. Australia.
Description.An evergreen tree with large, alternate, often pubescent leaves up to 40 cm long, similar to fern fronds, consisting of numerous leaves. Leaf shades vary from light to dark green, sometimes with a bluish tinge. The flowers are white, red, yellow or orange, appearing at the tops of the branches, in racemose inflorescences. Large straight or slightly curved pistils make Grevillea flowers look like splayed tassels.
Height. Under natural conditions, it can reach a height of 30 m. In cultivation, when grown as a houseplant, the height is 45 - 180 cm and is well regulated by pruning.
They can propagate by seeds, but this operation is quite complicated and can be done mainly by specialists. Semi-ripe cuttings 5 - 10 cm long in summer. Plant them in loose, moist soil and keep warm at a temperature of at least 18 ° C, preferably with bottom heating.
They can live indoors for a very long time with proper care. Mature plants sometimes lose their decorative appearance.
Grows well in hydroponics.
In its natural habitat it is a tall, fast growing, evergreen tree up to 40 m with an elongated crown. The plant has very attractive, complex, dissected leaves. The surface of the leaf plates is glossy, green, the underside is often painted in a lighter shade. During the flowering period, the plant abundantly forms oblong inflorescences with many petalless flowers with long, orange-red stamens.
An interesting feature of the plant is that it loses some of the leaves before flowering.
Extremely spectacular and at the same time compact shrubs with a dense, spreading crown, formed by abundantly branched, long shoots. The leaves are narrow, linear, reminiscent of needles, reach a length of 1 - 3 cm, painted in green or bluish - green, densely cover the stems. During the flowering period, the plant adorns itself with small apical inflorescences, consisting of red, pink or crimson flowers.
Tall sprawling flowering shrub or low, evergreen tree up to 7 m with thin, graceful branches. The leaves are compound - consist of many linear, green segments. In spring and summer, cylindrical inflorescences appear on the tops of the shoots with many pink, red, less often white or cream flowers with long, curved and fluffy stamens.
Small evergreen shrubs with a rounded, lush crown up to 2 m high. Dark green or bluish green, needle-like, needle-like leaves have a glossy surface and abundantly cover the stems of plants, reach a length of 1 - 4 cm. Bright pink or cream flowers appear on the plant in spring or summer in small apical inflorescences.

This interesting plant came to us from subtropical forests, where it blooms very beautifully. In room conditions, it is grown solely for the sake of thin pinnate leaves. It is not difficult to get Grevillea at home, given that it reproduces well by seeds.
Grevillea powerful - an evergreen ornamental plant from the Proteus family, originally from the humid subtropical forests of Australia. In nature, it reaches 20 m. Her flowers are orange, collected in brushes. Unfortunately, at home, it is practically does not bloom but sometimes it happens.
I first learned about Greville when I saw an advertisement for seeds in one of the magazines. The photo showed a plant with fern-like leaves that was labeled "Australian Silk Oak". Since then, I have been looking for the seeds of this exotic in the catalogs and only in January of last year I bought a powerful variety Grevillea Green Island.
seeds were large, flat, dark brown. They quickly lose their germination, therefore, following the instructions, immediately sowed them into a mixture of leafy, soddy, humus soil and sand (2:1:1:2) to a depth of 1 cm, poured warm water and put on a shelf in the kitchen, where the temperature is 22-25 ° C. Two weeks later, the first green sprout appeared, two days later, another one. Moved the flowerpot to the most bright and warm window, but there were no more shoots.
When the second leaves appeared, dived plant in pots with a diameter of 10 cm. soil for them I prepared from leaf, coniferous, peat soil and sand (1: 2: 1: 0.5) with the addition of brick chips. It must be acidic. Watered profusely. After two weeks, new leaves appeared on the Grevillea. In the spring, the plants were shaded a little from the bright sun, but they were not removed from the window. Babies need a high temperature for growth - not lower than 24 ° C.
In June, when the weather is warm, took the pots out to the garden and put it in partial shade under an apple tree. Polivala regularly with soft spring water. Often sprayed. When the terrible summer heat began, she poured fine gravel into the pan, poured water and put the pots on the gravel. The plants immediately raised their beautiful leaves with silky pubescence.
fed seedlings twice a month with a weak solution of fermented grass. Top dressing stopped in October, when brought plants into the house. By this time, the Grevilleae had grown to 25 cm. wintered on a bright but cool window, where the temperature does not exceed 15 ° C. I watered them moderately, but did not overdry the earthen ball. I often ventilated the room. spring transplanted grown plants in larger pots.
In order for the crown to be compact, the plant needs pruning. young plants transplanted annually, older than three years - every two years. propagate grevillea with semi-lignified cuttings, which are cut in August and rooted in a greenhouse in diffused light.

Hello everyone! Tree-like grevillea with filigree greenery. Home care with photos and videos in this material. Grevillea is one of the most unusual maxi-sized houseplants. Of course, it does not compete in size with palm trees or large lianas, but it makes a bright impression: a “curly” tree, lush and voluminous, very elegant.
But at the same time, Grevillea also manages to look very airy, does not weigh down the rooms and brings filigree greenery and freshness to the atmosphere. She needs a cool wintering, otherwise the care of Grevillea is simple.
What you will learn from this article:

Grevillea(Grevillea) is a small genus of ornamental plants that are actively used in ornamental floriculture. As part of their natural habitats, in Australia, grevilleas are real giants, growing up to 35 m in height. In room culture, they are much more restrained and will not exceed 2 m, and often even more compact. At the same time, the height of the plant itself is easily controlled by pruning.
The most widespread in room culture is the species, which is also called silk oak. Grevillea large, or powerful (grevillea robusta) - a tree-like herbaceous plant with feathery leaves, which at first sight evoke associations with ferns. Thin pinnate leaves with a filigree section of lobes in length reach 30 cm and are the main pride of Grevillea.
The foliage colors of this beauty range from forest green to green-bronze or silver, while growing conditions often change the base tone to a brighter or, conversely, darker one. An attractive gloss only adds beauty to it: thanks to the shine, the plant always seems radiant and fresh. At room conditions, it will not be possible to enjoy the flowering of Grevillea: it can only bloom when grown in open ground.
A distinctive feature of all Grevilles is a fairly intensive growth. They grow quickly, under comfortable conditions and proper care - rapidly, constantly increasing their height, volume, becoming more and more beautiful. Modest plants in the form of small bushes quickly transform into original trees. But the use of this plant in the interior is also very unusual: grevillea is a culture that can only be exhibited as a soloist, in splendid isolation.
Grevillea belongs to the medium-difficult-to-care plants. Due to the need to provide conditions for a dormant period that are not typical for living rooms, this beauty is not suitable for everyone. Yes, and care for watering should be scrupulous. But Grevillea responds to good care with the amazing beauty of greenery and rapid growth.
There is a lot of controversy about the correct selection of lighting for the Australian beauty. Due to its natural adaptability and large size, Grevillea adapts well to any light or partially light location. And in many ways, where the Grevillea will grow more comfortably depends on the growing conditions of the plant before buying or propagating.
The standard solution is a bright location with diffused lighting, but without direct sunlight. But grevilleas will not suffer from a sunny location, and from light partial shade. The best choice is to observe the plant in various conditions and stop at the place where Grevillea grows best and does not change the color of the leaves.
Too much shading will cause the leaves to drop. In addition, deviations to a leaner or sunnier location result in leaf discoloration, which may lose its bluish and bronze tints or become faded.

Grevillea is not the most heat-loving plant. It prefers to grow in cool conditions and does not tolerate heat very well, which invariably affects the attractiveness of the leaves. This beauty, even in the warm season, is best kept at a temperature of 10 to 20 degrees Celsius (maximum figures - 23 degrees).
In the cold season, when Grevillea stops growing and is at rest, it is better for the tree-like beauty to ensure a change in conditions to even cooler ones. The optimum temperature from November to the end of February is from 5 to 10 degrees, in extreme cases - from 8 to 15 degrees body. If Grevillea is kept in typical room conditions in winter or suffers from heat in summer, the plant may shed its leaves (partially or completely).
When choosing a location for grevillea in your home, immediately draw a “circle” of the coolest places - the lobby, landing, foyer will suit the greville more than living rooms. But if you do not have such places, choose those locations in which there are no sharp fluctuations in temperature, the climate is the same throughout the year. Grevillea is often grown in cool-type greenhouses, in winter gardens with moderate heating.
For Grevillea, in addition to temperatures, access to fresh air is also of considerable importance. This plant is best grown in well-ventilated rooms where the air will not stagnate. Fortunately, the tender grevillea is not too afraid of drafts and does not need additional protection from air currents.
Thanks to such preferences, Grevillea is able to grow in the warm season not only in the room, but also in the fresh air. Its filigree greenery can decorate balconies, terraces, and seating areas in the garden. But when moving Grevillea to a new location, be sure to switch it to a more frequent feeding regimen and choose the right lighting, exposing the pot only within semi-shady and scattered locations.
Grevillea large (Grevillea robusta)
Grevilleas are quite moisture-loving plants. But the rate of moisture consumption from directly depends on the growth rate of the plant and its age. The older the tree becomes, the more frequent and plentiful watering it needs. Grevillea does not tolerate stagnation, but likes medium rather than light substrate moisture. Between waterings, only the top soil in the pot should be allowed to dry out, and excess water should be drained 4-5 minutes after watering.
Drying of the soil should not be allowed not only from spring to autumn, but also in winter. True, in the cold season, watering should be reduced so that the humidity is only light, less than during the plant's stay in a warmer environment.
But the main parameter of irrigation for Grevillea is the quality of the water. Only soft water can be used for this plant.
It is worth paying attention to the humidity of the air. Grevillea leaves will be more beautiful the more humid the plant grows in. Grevillea is not afraid of typical living room conditions, but if you provide her with increased humidity, the attractiveness of the tree will reach a new level.
It is not necessary to install humidifiers for Grevillea: this plant is fully content with spraying. But if you have the opportunity to use at least pallets of wet moss, you will save yourself a lot of trouble. The main thing is to spray regularly, in the warm season - daily.
Grevillea loves top dressing. And this is easy to understand: the rapid growth of greenery requires appropriate compensation for the depletion of nutrient reserves in the soil. If the plant is taken out into the open air, then it needs to be fed weekly. In room mode, from March to early October, feeding should be less frequent - every 2-3 weeks. Grevillea does not need to be fed during a cool winter.
For this plant, it is better to use complex, universal fertilizers, and not mixtures for decorative and deciduous crops. Indeed, despite the fact that Grevillea does not bloom indoors, it does not at all become a purely deciduous crop and for normal development it needs a balance of nutrients, and not just nitrogen.
This Australian beauty tolerates pruning very well. Growth inhibition, crown thickening can be carried out regularly, annually, before transplanting and the start of active growth. Without pruning, pinching or shortening the tops of the shoots, Grevillea stretches, large gaps appear between the leaves.
It is better to transplant Grevillea when necessary, and not on schedule. But since the plant grows quickly, it usually changes the substrate and capacity annually. If you have an old Grevillea and don't repot it every year, be sure to remove the topsoil and replace it with fresh. But during the procedure, be careful not to damage the roots of the plant. It is best to transplant at standard times, after the start of growth in late February-early March.
The soil mixture for Greville should also be specific. These beauties prefer to grow in clayey in texture, but loose, containing a high percentage of humus and certainly acidic substrates.
Grevillea should be carefully selected containers. This plant is grown in medium-sized pots, because Grevillea does not like too much free soil, developing in such conditions at the expense of the attractiveness of greenery.
The main threat to all Greville is spider mites. If measures are not taken for the plant to increase the humidity of the air, grevillea grows in an almost dry climate, these pests quickly find comfortable conditions for living and breeding.
To fight the spider mite, you should regularly, with a frequency of about 1 time per week, inspect the foliage and, at the first sign of damage, take measures to increase air humidity and spray with insecticides.

New grevilleas at home can be obtained from seeds. Their sowing should be carried out in early spring, along with the first garden summers. They are sown in large containers or boxes, in a light universal substrate. They germinate only in warmth, at the usual room temperatures. In this case, the inputs appear unevenly. Dive is best done only after the appearance of the second true leaf, in individual pots.
You can try to get new plants from half-ripe cuttings, which are cut from low shoots, not branched and thin, cutting them along with the "heel" in August. Grevillea cuttings take root not in the substrate, but in moistened sand. Treatment with growth stimulants is required.
Grevillea at home
Grevillea (Grevillea, family Proteaceae) is a fast-growing shrub or tree with lacy, fern-like leaves. The underside of the leaf appears silky, covered with soft hairs. Grevillea flowers are orange, collected in brushes. Grevillea is native to the islands of New Guinea and Australia.
One type of grevillea is grown in the room - powerful grevillea (Grevillea robusta). If you're looking for an inexpensive indoor tree plant, Grevillea is the one to go for. It is easily propagated by seeds or cuttings and in one year grows up to 30 cm in height, and after 4-5 years it reaches the ceiling.

Grevillea feels good in a bright and cool room. In summer, it can be taken out into the garden or onto the balcony, it is only necessary to shade the plant from direct sunlight. The temperature is required moderate or slightly below moderate, in winter not lower than 5 - 8 ° С. Grevillea tolerates the dry air of rooms well, but it is useful to spray the leaves from time to time.
Grevillea (Grevillea)
Grevillea is watered abundantly from spring to autumn, moderately in winter. From April to September, a complete mineral fertilizer is applied twice a month. To stimulate the growth of young shoots, Grevillea must be severely pruned. The plant is transplanted up to three years every spring, subsequently - after 2 years. Use a soil mixture of, peat, humus, leafy soil and sand in a ratio of 1: 1: 1: 1: 1.
Grevillea (Grevillea)
Grevillea may be affected. On the underside of the leaf, clusters of small white insects and their larvae can be found. The plant must be treated with Actellik and rearranged to a drier and brighter place.

Grevillea is a hardy plant whose natural growth environment is the subtropical forests of Indonesia, Australia, and New Guinea. There are more than 260 species of evergreen trees, shrubs and flowers of Grevillea.
Under natural conditions, shrubs of this species are found, and their height does not exceed 1 meter. But the trees grow and can reach 35 meters in height. Indoor grevillea does not grow above 2 meters, it is used to decorate bright and cool rooms.
In nature, Grevillea blooms, but in a room it never happens. But even without flowering, the plant is very beautiful, it is distinguished by lace leaves up to 30 cm long, which are covered with a silvery fluffy border from below. Outwardly, these leaves are very reminiscent of a fern, although they look more elegant.
At home, you can grow these types of grevillea:
Growing from seeds begins at the end of winter or in the first days of spring, the shrub does not like heat and grows better at this time. Sow seeds in soil mixed in the following proportions: 2 parts sand, 2 parts humus and 1 part soddy land. And the soil for transplanting seedlings should be more acidic, it consists of leafy, coniferous, peat soil and sand.
Growing Grevillea is no different than growing our simple flowers. Just prepare the soil, carefully place the seeds in it, cover them with earth, sprinkle with a spray bottle. That's it, now you can cover future seedlings with glass or polyethylene!
Place the seedling box in a room with a temperature not exceeding 17-20 ° C, ventilate it regularly by removing the glass. The fact is that young shoots need fresh air.
The growth of this shrub is uneven, so the dive is carried out as the seedlings grow. Threw away the top 2 leaves? Then you need to transplant into a separate pot. And after 3-4 years, the shrub will easily rest against the ceiling with its crown.
Young seedlings are transplanted every spring, and adults - a year later.
The shrub is not capricious and tolerates heat well in summer. But before the start of the heating season, a flowerpot with a plant can be taken out to the veranda without heating with a temperature of at least 6 ° C. In winter, he just needs low temperatures. The growth of the shrub is beneficially affected by frequent airing of the room.
Suitable lighting for Grevillea is diffused light, in season - subdued sunlight. Never put a shrub under direct light, as this can kill it.
The plant responds well to air humidity. At low - sick, and at high - grows well. If the humidity in the room where the flower is kept is low, then it is worth spraying the bush with a spray bottle.
In the spring and summer, the shrub is watered as the top layer of the soil dries out. With the advent of autumn, watering is minimized so as to prevent complete drying of the soil. Only settled water of the temperature in which the flower is contained is used.
From early March to mid-September, Grevillea enters an active growth phase, and it needs top dressing. Mineral fertilizers are used once every 2 weeks, but it is better to refuse organic matter.
The shrub grows very quickly, so it needs timely pruning. Pruning is important not only for the correct formation of the crown, but also for slowing down the growth rate. Without it, the plant will reach the ceiling in 1-3 years, and at that moment it will be too late to fix something.
The plant propagates by seeds and cuttings. We have already talked about seeds, now let's talk about cuttings.
For propagation, plants choose cuttings with unbranched shoots. They are carefully cut, and then rooted in moist soil. For 1–2.5 weeks, the shoots take root.
Weak plant growth indicates a lack of nutrients or the wrong soil. If you notice that Grevillea has frozen in growth in one place, then you should start fertilizing every 2 weeks, and with the onset of spring, relocate the plant to a new land.
As a result of poor watering and complete drying of the soil, the plant does not dry out, but simply sheds all the foliage. To save the plant, dip the pot with it in water at room temperature for 30 minutes.
Yellowing leaves mean the plant is hot. This happens in winter if the owners forgot to move the grevillea to a cool balcony or veranda. Because of this, a spider mite, characteristic of dry and very warm rooms, settles on the plant. To get rid of the pest, wash the plant in the shower and try to spray it regularly with water.
Grevillea suffers from whiteflies. These are small flies that fly in silver flocks from leaf to leaf. And it can be mistaken for dust, but they have a detrimental effect on the plant. If you notice them, then you need to treat your grevillea with an insecticide.
Grevillea is an evergreen, fast-growing plant that came to us from Australia. It gained its popularity due to the unusual shape and color of the foliage and abundant flowering.
The genus of this plant has about 200 species, radically different from each other. At home, representatives of the culture can take the form of large trees with a trunk height of up to 35 m or be creeping shrubs no higher than 50 cm.
Grevillea is cultivated as a houseplant thanks to its thin pinnate leaves, which reach a length of 30 cm.
It is almost impossible to achieve flowering with indoor cultivation and maintenance. The plant needs high humidity and does not tolerate the winter season with its artificial heating. However, if all conditions are met, the shrub will please with abundant brushes of different shades with many tubular flowers, twisting perianths and long columns.
Most often, grevillea is placed in cool and bright rooms in which it is given the main role (without being adjacent to other indoor flowers). With proper care, the height of the plant can reach 2 m.
Grevillea loves cool conditions and high humidity. The pot with the plant should be placed in a well-lit room. In no case should direct sunlight be allowed to enter, especially in the spring and summer.
In the warm season, indoor trees are taken out into the street and placed in places with diffused light, excluding drafts or strong gusts of wind.
During the spring and summer months, grevilles provide a temperature regime within + 19 ... + 24 ° С. From late autumn and all winter, the plant should be placed in a room with a temperature not higher than + 12 ° C.
Grevillea is easy to care for. The main thing is to water on time, avoiding stagnation of moisture and severe drying of the soil. The plant needs regular spraying to create the humid climate of the Australian forests.
To form a crown, it is necessary to regularly correct its shape by cutting off protruding branches. If pruning is not carried out, the plant begins to intensively stretch upwards and can reach large sizes.
For planting, you can purchase a special acidic soil used for growing heather plants. To prepare the soil yourself, you need to take 2 parts of coniferous, 1 part of leafy and 2 parts of peat soil, dilute with coarse sand and perlite.
Like all houseplants, Grevillea needs to provide drainage by lining the bottom of the pot with expanded clay or medium-sized stones.
Every spring, the flower is transplanted into a not very deep pot, slightly larger than the previous one. Pre-prepared soil is used. The plant after the procedure needs to be observed for some time for diseases.
Grevillea is propagated by planting seeds or cuttings. Growing from seeds occurs in late winter or early spring. The soil for planting is prepared from leaf, sod, humus soil and sand in a ratio of 1: 0.5: 0.5: 1, pour it into small pots and slightly deepen the seeds. To maintain optimal temperature and humidity, the container is covered with glass or a plastic bag.
Shoots may appear unevenly. Transplantation of sprouted seedlings occurs only after the second full-fledged leaflet has appeared. Sprouts are planted in separate pots or in 1 box at a distance of 3 cm from each other.
For reproduction by shoots in August, a semi-ripe stalk is cut from the flower and placed in moistened sand. After the branch takes root and continues to grow, it is planted in a pot with a diameter of 7 cm with an acidic substrate.
From early spring to mid-autumn, Grevillea has a period of intensive growth, so it needs regular feeding. In this case, complex fertilizers for deciduous indoor plants are used, which must be applied 1 time in 2 weeks.
In the autumn-winter period, it is not necessary to fertilize the soil. The main thing is to provide the flower with sufficient lighting and low temperature, since this period is a dormant time.
The main problem in growing Grevillea is improper maintenance, especially during the dormant period:
If the necessary microclimate is not reached in the room with the plant, a spider mite may appear on the foliage, which covers the shoots and branches with a thin cobweb. They begin to turn yellow, deform and fall off. If such a problem is found, you should immediately treat the bush with an insecticide, increase the humidity of the air and do not forget to regularly inspect the flower.
Rosemary (grevillea rosmarinifolia) is a shrub that can reach a height of 180 cm. The crown is pubescent, with leaves about 10 cm long with narrowed ends. The top of the leaves are smooth, the bottom they are covered with a silky fluff.
The rosemary-leaved species has red flowers collected in multi-flowered racemes with a 1 cm curved tube.
Green Island is an evergreen shrub 2 m high with an average growth rate. The crown of this tree needs constant pruning.
Powerful (grevillea robusta) is a tree-like representative of this genus of plants, which is also called Silk Oak. The cone-shaped crown, reaching 3.5 m, looks beautiful. The leaves are 15-20 cm long and have a dissected shape, smooth on top, covered with yellow fluff below. Bright orange flowers are bisexual, can reach 12 cm in length.
