Rare types of hydrangeas

If in your garden hydrangeas of habitual forms are already growing, and you are a fan of these plants, it is time to try cultivating rare forms. Of course, such plants will require more care, because it is not known how quickly they will take root in the conditions of your site and whether they will wish to make you happy with lush flowering. But the road will be mastered only by going, and in any case it is worth a try!

Rare forms include serrate, Sargent, rough, oak-leaved, Bretschneider and, perhaps, ashen — all these names of types of hydrangeas in any grower on hearing, but few decided on their breeding. If desired, any types of garden hydrangeas can be found in Russian stores or catalogs. It is worth noting that all of them are quite heat-loving (the city of ashen is a separate story), they should be planted in the most comfortable place protected from the winds and sheltered for the winter. They bloom in the middle lane, with the exception of oak-leaved hydrangea, will be almost annually, but, of course, not as elegant as in Europe.

On this page you will learn what rare types of hydrangeas are and how to care for them.

Ornamental shrub hydrangea Bretshneider

By habit, the ornamental shrub of the Bretchneider hydrangea, found in 1882 in the vicinity of Beijing, is more like a lilac or a large bullfinch. Its height is up to 4 m. It can grow in the form of a bush or tree, it is very hardy, durable, does not bother with shoots, does not require any props. Compared with other hydrangeas - drought resistant. This miracle blooms annually and very abundantly, becoming covered with slightly fragrant buds with a diameter of about 15.

As can be seen in the photo, the flowers of the Bretschneider hydrangea are initially milky-white, later they turn pink and purple:

The color of the inflorescences may change with changes in soil acidity. In this type of hydrangea flowers are collected in large umbrella, slightly convex shields, which are kept on the plant for a long time, until late autumn.

Fruits - dry boxes - ripen in September. It blooms with 5-6 years.

Breeding hydrangea Bretshneider (N. bretschneideri) seeds and cuttings.

Cuttings are usually rooted without problems. The hydrangea root system is superficial and branched. Hydrangea can grow in partial shade and in the sun. And in full sun, it blooms better, but there it needs to be watered, otherwise the leaves may dry out and burn.

Dislikes calcareous soils and windy places. Does not tolerate winter moisture, the soil should be sufficiently permeable.

Pruned shrubs prior to sap flow. Strong withered shoots shorten to a well-developed node with buds, cut out all the old, weak and frozen. Hydrangea is fed with special fertilizers for hydrangeas rich in magnesium and iron.

Hortensia Bretshneider - a unique plant. This is a magnificent background in the shrub mixborder, a constituent element in the bush group that you want to see in bloom in the second half of summer.

Look at the photo - this type of hydrangea looks great in the fall and winter in combination with viburnum, hawthorn, Kyone rowan (with white fruits):

With these plants, hydrangea looks interesting also in the summer due to contrasting foliage.

For a long time, the hydrangea of ​​Bretschneider was impossible to buy. Now she began to grow domestic nurseries.

Occasionally found in Western European nurseries varieties of hydrangea Bretschneider:


'Jermyn's Lace'

The diameter of their inflorescences is gigantic - from 25 to 30. See how varieties will feel in central Russia is unknown.

Hortensia serrata: photo and description of varieties

Hydrangea serrate (N. serrata) - close relative large hydrangea. At home, in the mountains of Japan and Korea, it is an erect shrub about one and a half meters in height. Its foliage is different from the foliage of the large-leaved hydrangea. It is smaller and narrower, sometimes even lanceolate.

Pay attention to the photo - the inflorescences of the serrate hydrangea are slightly convex, corymbose:

In the central part of the fertile flowers, on the periphery of the relatively large rare sterile - white, pink or bluish. Pink and blue can change the color of the inflorescences, depending on the acidity of the soil. Hortensia serrata is unusually good in July-August during flowering.

Delivers light partial shade. When caring for this type of hydrangea requires a mandatory shelter for the winter. As a shelter, it is recommended to wrap the bush in burlap, ruberoid and be sure to spill inside with dry leaves. If the bush manages to bend, the chance of a happy winter will increase. Due to the complexity of the shelter Hydrangea serrate is grownmainly in the southern regions, in the north it is prone to frosting. This is important because the inflorescences are laid, as a rule, on last year's shoots. Although sometimes inflorescences appear on new shoots growing from the lower buds.

In hydrangea serrata varieties very much. They are compact, used for container growing.

The most famous variety is 'Blue Bird' with bright blue color of sterile flowers. The middle is dark blue.

In the variety 'Preziosa', almost all flowers are sterile.

As they bloom, their color changes from light pink to purple. Soil acidity does not affect the color of flowers.

'Spreading Beauty' interesting prostrate shape of the bush and fiery autumnal color foliage.

'Golden Sunlight' different yellow foliage, especially bright at the beginning of the dissolution. Flowers in pink.

Decorative garden shrub Sargent hydrangea

Sometimes the ornamental shrub Hydrangea Sargent is considered as a subspecies of a rough hydrangea (N. aspera ssp. Sargentiana).

The birthplace of Sargent hydrangea is Central China. In nature, large shrubs up to 3 m tall. In central Russia reaches 1-1,5 m in height. With age it expands greatly in width. The bush is not falling apart, with thick shoots.

As seen in the photo, the leaves of Sargent hydrangea are very showy, large, dark green, covered with thick hairs, as if velvet, very pleasant to the touch:

Hydrangea blooms regularly in July.

The inflorescences are flat, corymbose, 16 diameter, see. Fertile flowers are pale purple, sterile flowers are white. It is impossible to bend the plant to the ground, so the shoots in the fall are cut short. The short lignified part and the near-stem circle are covered with a dry leaf or spruce branches.

Sometimes, to protect against cold, the base of the bush is mulched, and the crown is tied with a covering material — lutrasil, spanbond, and then kraft paper. With such a cover, the shoots can survive if winter turns out to be favorable. If you are not lucky - nothing terrible, the shoots, as already mentioned, will grow back.

Early in the spring, as soon as the danger of severe frosts is past, mulch and kraft paper are removed, but not before mid-April. This work is carried out on an overcast day, towards evening, so as not to cause a burn by the rays of the bright spring sun. The most thermophilic of the hydrangeas mentioned in this book belongs to the 7 zone according to the zonal gradation system adopted by the US Department of Agriculture and used in other countries.

Rough hydrangea

Rough hydrangea (N. aspera) hails from the Himalayas and western China. Looks like Sargent hydrangea, also pubescent. In nature, it is a small tree or shrub in height from 4 to 10. The leaves are somewhat smaller and narrower than those of Sargent, with serrate edges and a long curved end. The diameter of the inflorescences - see 25.

Look at the photo - this type of garden hydrangea has white, pinkish, bluish, sterile flowers with jagged petals, the center of the inflorescence is purple:

Winter hardiness in hydrangea rough is the same as that of Sargent, therefore plants require the same care.

Rough hydrangeas have varieties, but they are not too different from each other.

Some of them are grouped together. Villoza (Villosa Group).

Among them are '' Velvet Lace 'with inflorescences in lilac-violet tones and' Anthony Bullivant 'with pink sterile flowers and violet -growers.

Perhaps, of all varieties of rough hydrangea, the most interesting are 'Peter Chappell' и 'Macrophylla'.

The first one has a light, sterile white-colored flowers with wide jagged petals, the second one has pinkish, bhromchatye-shaped sterile flowers.

Ornamental shrub ashen hydrangea (with photo)

Homeland of ornamental shrubs ashen or sulfur hydrangea (N. cinerea) is the east of North America. She is very similar to tree hydrangeaIt differs from it by a well-defined grayish pubescence on the lower part of the leaf.

The photo shows that the ashen hydrangea forms large hemispherical inflorescences:

The height of the shrub is 1,1- 1,5 m. The GBS RAS is grown from 1954 g. (Seeds were obtained from Amsterdam and Turin).

The problem is that not all taxonomists recognize the independence of this type. In serious foreign reference books the plant is called N. arborescens var. discolor, that is, a hydrangea tree, varicolored variety. But that's not all.

There is an old hybrid (before 1860) - grayish hydrangea (N. x canescens), which also has a grayish hair on the underside of the leaf. Since all three hydrangeas (species tree variety is multi-colored, ashy and grayish) have long been in culture, there is hardly anyone able to distinguish them.

What is the business gardeners to the subtleties of taxonomy? Direct. The plant you planted may have different winter hardiness. Option two. The first is that it is equal to the winter hardiness of tree hydrangea. The second - the plant can withstand the temperature drop to -23 degrees. In this case, the shrub is suitable for landscaping the southern regions of Russia.

Gray hydrangea 'Sterilis', which can be found in garden centers, is similar to the hydrangea tree' Grandiflora ', but it has a gray lower side of the leaf and less of sterile flowers in the inflorescence.

Then you can see the photo and description of the oak-leaved hydrangea.

Oakolistnaya hydrangea: photo and description of varieties

Hortensia oaky (N. quercifolia) - the most exotic among the other hydrangeas. This is a North American plant 1,5-3 m in height. Its “zest” is pleasant to the touch textured leaves, resembling red oak leaves. Such leaves are the main difference of this form from other species of this shrub.

As shown in the photo, in the Dubolian hydrangea the edges of each leaf are sharp, with notches:

Leaf size - up to 25. See Fresh shoots and young leaves covered with a light white fluff, which disappears with time, remaining only on the underside of the leaf. In autumn, the leaves turn purple-red.

The hydrangea is huge, to 30, see paniculate inflorescences with a predominance of sterile flowers, which initially stand like candles, then gradually incline. Unfortunately, in central Russia, it practically does not bloom. Experts suggest that it is not only a relatively low frost resistance of the shrub (it can withstand a short-term decrease in temperature to -29 ° C), but not enough sunny days.

Where the climate is milder and the sun is bigger, varieties of oak-leaved hydrangea are popular:

'Snow Flake'

'Snow Queen'



У 'Snow Flake' terry flowers

'Snow Queen' - white

For 'Garmony' spherical or flat large inflorescences with a diameter up to 20 are characteristic. See Petals have a white or cream color.

When describing dubolistnoy hydrangea particularly worth highlighting 'Applause' gradeshrubs which reach a height of 2 m and have large inflorescences of snow-white color.

Young plants should always be covered for the winter or transplanted into a pot and kept indoors as a room flower during this period of the year. In mid-December, the shrub loses foliage and retires. During this period, it is worthwhile to move the hydrangea to the dark cool corner of the room and reduce the frequency of watering. Awakening occurs in April - buds begin to swell on the branches of a bush. During this period, hydrangea must be put on the window sill so that the plant receives enough light. It is watered by adding fertilizer to the water. Back to the garden plot shrub planted in May.

With age, shrubs tolerate cold much better. If hydrangea does not bloom in principle, it does not make sense to save the shoots. Then in the base of the plant, you can simply pour an armful of fallen leaves. The bush will freeze to the ground almost to the base, but will definitely grow.

In the southern and western regions of the country, hydrangea can not dig for the winter, but be sure to cover. This procedure is performed in dry weather in autumn - in October-November. The branches of the plant must be bent to the ground and covered with non-woven material. The same material or spruce frail and laid under the stems. On top of the covering material it is necessary to pour peat with a layer of about 15 cm, covering it with a film.
