We always had it in our garden when i was young,.. i did sow some seeds two years ago but when the seedlings appeared i gave them all to a friend who had started a huge rock garden,..i didn't mind giving them away as i had lots of Campanula to substitute,..where the plant thrives,..Rockeries,..Walls,..well drained or sandy soil,..cutting back after blooming helps also take Root Stem Tips to replace dead spots and you should have Aubrieta for years,..fingers crossed for your seeds sown for the coming season
