Description of the variety

The fabulous name Schloss Wackerbarth translates as "Wackerbuff Castle" (can be read as Wakerbays, Wackerbarth) in honor of the castle of the same name, located near Dresden and turned into a winery.

The variety belongs to the large-leaved hydrangea species Hydrangea macrophylla. It is a chameleon - the flowers gradually turn from green to creamy pink, and then acquire an exotic color: red-crimson petals with strokes of lime green around the edges and a blue-violet center.

Such a description does not convey all the shades - they change depending on the place of planting and the growing conditions of the plant. In autumn, the flowers turn green, a red border appears. The intensity of the color depends on the acidity of the soil - the higher, the brighter.

Flowers are formed on the shoots of the second year and are collected in spherical inflorescences up to 15-30 cm in diameter. Flowering is abundant and lasts from summer to mid-autumn.

The bush is erect, lush, grows up to 1.3 m and 80 cm wide, and multi-colored inflorescences may be present on one branch. The leaves are large, shiny, dark green, with a patterned edge.

The variety is frost-resistant - it winters well at -18-20⁰C under cover, but it can withstand even more severe frosts.

Landing features


Planting is carried out in April-May, when the soil is already warmed up enough. The bushes planted in spring have time to get stronger before wintering. In the southern regions, it is permissible to plant hydrangeas in the fall.

Organization of the place

This variety prefers shaded areas with nutritious, loose, well-drained and acidic soil.

The brightness of the color of the petals depends on the quality of the soil, since the aluminum salts, which affect this, are assimilated only in an acidic environment.

Neutral and alkaline soils reduce the decorative effect of the plant, and the leaves can be affected by chlorosis.

The ideal location is partial shade with sun exposure in the morning and evening hours. Due to the growth in the sun, the bush withers. It is desirable that the site be protected from drafts.

Planting holes should be approximately 50 cm deep and wide. The distance between the bushes should be about 1-1.5 m, but it is enough to leave 0.5-0.6 m in the hedges. The holes are prepared two weeks before planting so that the soil has time to settle.

Preparation of planting material

For landing you will need:

  • light nutritious soil mixture: 2 shares of peat, 2 shares of garden land, one share of humus and fallen needles. If the soil is alkaline, then it can be acidified or treated with iron chelate.For the manifestation of a brighter blue tint of the inflorescences, ammonium sulfate can be added to the soil;
  • drainage - small stones, broken brick, pebbles;
  • mulch to prevent the roots from drying out - peat, chopped bark, needles;
  • a healthy seedling must have at least two shoots and a healthy root system without whitish bloom and moldy smell; for better survival, it is better that the length of the roots is above 30 cm. Hydrangeas can be purchased in containers; open-root seedlings should be planted as soon as possible.

Landing technology

  • A drainage layer is laid at the bottom of the planting pit;
  • A seedling with open roots is immersed in water for a while, or watered abundantly if it is in a container. Then they are placed in the wells. If necessary, spread the roots;
  • The hole is sprinkled with a soil mixture to form an earthen mound. The soil must be periodically compacted by hand;
  • The resulting earthen circle is sprinkled with mulch.



Large-leaved hydrangea is a moisture-loving plant, therefore, a clod of soil should always be in a moist state, but not wet. It should be watered with rainwater from a barrel or tap water poured into a barrel and warmed up in the sun. It is recommended to organize drip irrigation.

Watering is best done in the morning or evening at the rate of at least two buckets of water per week per bush. At the end of August, watering is reduced to a minimum.

Top dressing

The variety responds well to top dressing, which should be applied under the bush twice a season - at the beginning of summer and during the budding period. Mineral complex, potash, phosphate fertilizers are suitable for this. The plant also responds to organic fertilizers, for example, to a mullein solution.

Gardeners share one secret: if you add alum on only one side of the bush, then it will become multi-colored.


Large-leaved varieties of hydrangeas practically do not need pruning. In early spring and autumn, shoots can be shortened for sanitary or decorative purposes. Since flowers appear on last year's shoots, their regular cutting can lead to the cessation of flowering.


Reproduction is carried out in the spring using the following methods:

  • green cuttings of last year's shoots that take root in greenhouses;
  • layering of annual shoots - scratch the bark in the middle, bend the branch to the ground, sprinkle the middle part of the shoot with buds with soil;
  • dividing a bush is a traumatic method, each resulting bush must have a point of renewal.

With good rooting, seedlings can be planted in a permanent place in the spring after a year.
