How to Grow Aubretia
Aubreita is a low growing evergreen perennial which forms a mat of flowers and is good for the front of a border or better still, tumbling down a wall.
Aubretia is fully hardy and flowers best in a sunny spot but will grow in semi shade. Aubretia prefers well drained soil and will tolerate drier conditions which is why it is so well suited to walls and rockeries. It requires next to no maintenance and is trouble free. To keep a compact shape cut back after flowering. Aubretia is best cut back by about 50% and it can simply be sheared. Doing this prevents the plant developing an open, bare center. It is best to cut back immediately after flowering, cutting back later in the year may interfere with the plant's flowering next year. However do not cut over winter.
Although Aubrieta is not scented, it is attractive to bees and long flowering.
Aubretia flowers are in shades of light blue, mauve and pink and some varieties have variegated foliage, all are low growing, small plants.
Although a very simple and common garden plant, it is a lovely sight in spring to see a well established Aubrieta trailing over a wall a mass of blue, purple and pink; Aubreita always look really pretty and a make cheerful splash of colour.
Aubretia tend to be short lived plants as they can become bare in patches with age. To combat this take cuttings as Aubretia root very easily. Just trim off a cutting a few centimeters long in mid summer and root into well drained compost. Let the plant grow on to a mature size in a suitable container, and then it is ready for planting out.
Because Aubretia roots really easily you can, when cutting the plant back after flowering, just use these off cuts and plant them into containers and often they will root quickly.
Aubretia can be raised from seed if you want to cultivate a particularly colour or variety not commonly found in the garden centers, such as A.'Cascade red', which as the name suggests is a bright red variety, but otherwise the easiest way is to take cuttings.
