Blaukissen Royal Blue (Samen) - Aubrieta x cultorum

The 'Royal Blue' Aubrieta, in Latin Aubrieta x cultorum or Aubrieta deltoidea, forms pretty carpets of small blue-mauve flowers from March to May-June. This perennial plant, renowned for its abundant flowering, thrives easily in full sun on well-drained soil. Its evergreen leaves of silver-green color adorn the garden throughout the year. Perfectly suited for rockeries or the tops of walls, 'Royal Blue' Aubrieta harmoniously blends with other colourful varieties or covers the ground with taller plants in the garden or in pots.

Hybrid aubrietas belong to the brassicaceae family, mostly derived from Aubrieta deltoidea, native to southeastern Europe and Turkey. They are rhizomatous plants with a compact, mat-forming growth habit, forming cushions not exceeding 15 cm in height, which spread quite rapidly over an area of 60 cm. Their semi-evergreen to evergreen leaves, depending on the climate, are slightly silvery green and oval in shape. These are very hardy plants, able to withstand -20°C.

'Royal Blue' Aubrieta is a plant that requires little maintenance once established. It forms a low, spreading clump, suitable for all types of soil, provided it is not excessively dry. It is particularly well-suited for use as a border, in a rockery or on a slope, as well as for filling spaces between slabs or gaps in walls. In a rockery, 'Royal Blue' Aubrieta pairs nicely with asters, irises, Erigeron karvinskianus, and lavenders. For container cultivation, it can be planted at the base of alliums, tulips, narcissi, or shrubs. It is also ideal for hanging baskets, where its trailing stems elegantly conceal the container's edges.
