Sempervivums are a must have for any northern flower garden. These succulents provide excellent ground coverage for taller landscapes and can help block out weeds, grass and other unwanted growth. Also known as “Hen & Chicks”, these plants produce upwards of 2 ‘chicks’ per season, allowing them to spread easily. Hens can grow up to the size of a small dinner plate! These will come back year after year, saving you from having to put down mulch or landscaping stone!
