Alpinaria have many attractive plants from the Cabbage family. One of them is aubretia, which will take a little time to plant and maintain, but the result will be a magnificent flowering of this spectacular soil.
Aubrieta is found in southern Europe and the Middle East, where it was brought to our latitudes. It is a low, ramshackle perennial, whose shoots rarely rise above 10-15 cm above the ground.
As it grows, it forms a spectacular cushion. Leaves are small, green or blue, some species are slightly downy. There are varieties with motley leaves. An evergreen plant does not lose its leaves even in winter and retains its decorative effect at any time of year.
The genus consists of 12 species, which have a different flower palette. The colour of garden hybrids and varieties can be purple, purple, pink, blue and white. Flowering is so abundant that no shoots or leaves can be seen under the numerous small flowers.
The most frequently cultivated garden culture is the Aubrieta x cultorum, a hybrid of the Aubrieta deltoidea with other species. The hybrid blooms in May-June for about 40 days and unites a group of varieties that winter under snow.
A striking representative of the hybrid aubrieta is a cascading variety mix of “Giant Falls” with different flowering shades.
Other varietal forms in the garden design are purple-purple “Royal Violet” and “Cascade Purple”, pink-purple “Leichtlinii” and “Royal Red”, dark blue “Royal Blue”, early blue-blue “Neuling”, purple “Tauricola” and light pink “Royal Rose”. There are even varieties with terry flowers.
The choice of a place for an open field Aubrieta planting
For the plant to fully reveal its ornamental qualities, it is important to choose the right place to grow. Auburn in a temperate climate needs good sunlight which stimulates abundant flowering.
In the penumbra, green mass starts to grow actively, and flowering is scarce and short. Light shading is only possible in hot climates. Choose a warm, wind-safe place to plant your aubretia.
The soil should be low fertility, moderately humid, alkaline and permeable. The plant thrives abundantly on stony and lime soils that are nutrient-poor.
In addition, for planting obryetica seedlings, it is recommended to select an upland area to avoid overwetting and rotting of the bottom of the miniature plant.
Aubrieta maintenance for perennial planting
The attestation in care isn’t too demanding. Irrigation prefers moderate and even scarce watering as it does not tolerate excess moisture and is resistant to drought. Therefore, it is only irrigated with a small amount of water in heat and with prolonged absence of rainfall.
Twice during the season, a thin layer of coarse sand is poured under the roots to prevent moisture stagnation and rotting. In autumn, it is recommended to fertilise plantings with water diluted compost. Wood ash works well as a spring fertiliser.
Aubrieta care includes trimming the shoots after flowering. The procedure promotes the formation of dense, compact curtains and stimulates re-flowering at the end of the season. Before winter it is sufficient to cover the plant with a layer of fallen, dry leaves.
Sometimes the plant is affected by powdery mildew due to poor air circulation in high humidity conditions. Leaves are covered with plaque and deformed.
To cope with the fungus will help solution of colloidal sulfur or treatment with fungicides. Of the pests should be afraid of aphids, which are destroyed by soap solution.
