Bought 4 at the Master Gardener's sale. One was a "Black Knight" but can't remember the other three [lavender] cultivars. Two made it through last summer [and two did not]. They were under shade cloth on a frame, and bloomed gloriously all summer. They do like to sprawl, though. This Spring I pruned them down into a more compact shape and intend to keep tight control. Just checked, and lots of leaves, but no buds yet.
