This is a perinial herb and is one of the most important plants to grow.It is normally grown in the greenhouse in mid-February, and transplant out when they have some size and the danger of frost has passed.They grow long, woody stems that bear incredibly beautiful purple to blue flowers that linger through July and August.
By hand weeding they are kept free of competition and can often spot a self-seeded young one. They don’t seem to be especially long-lived or extremely cold resistant, but they do seem to be drought hardy. A rock gardener’s delight.
