What is the lifespan of Aubretia?
Aubrieta typically has a lifespan of 3 to 5 years. This longevity, combined with its potential for self-seeding, makes it a resilient addition to any garden. Understanding this lifespan is crucial for effective garden maintenance and planning. Cut back aubrieta after flowering (though not into any woody growth) to maintain the tight cushion shape and encourage a second flush of flowers. Try to make sure you do this every year, as otherwise aubrietas can become a little scruffy and bare in the middle.Aubrieta are an old favourite, pretty perennial alpine plants, great in the rockery, as ground cover or for edging a path. Aubrieta seeds can be sown from February to June or from September to October for flowering throughout the following summer.With a younger Aubretia plant which is in better shape, more compact, it requires only a light prune up to 5cms ( 2-3 inches max. In both cases prune in June when flowering has finished, or as soon as the Aubretia plant stops flowering in your area. It is best to cut back immediately after flowering.
