Germination 1-6-23 89% This perennial flower carpeting grows in Zones 4-9, likes temperate to cool weather with partial to full sun and slightly acidic soil types and is not a heavy feeder. Purple Aubrieta is a landscapers dream come true. It looks stunning on it's own and also makes for a nice border accent and brightens up boring-looking paver stones. It also attracts butterflies. Once established water moderately. To germinate, sow seeds on top of sterile potting mix. Press them down but don't cover them (they need light to germinate). Keep them in a temperate temperature and the seeds should be germinated within 2-3 weeks.
