How can one not love a drought-resistant, deer-proof, reliable blooming plant?
This one has lived here long enough for me to move babies to other places around the house. It makes itself at home wherever it goes. Does not take over, may make a baby if encouraged, takes pruning at most any time of year.
The bumble bees love these flowers. While I am smart enough not to test them, they are so engrossed in the blossoms they barely notice people around. Bumbles are not the only bees who savor this nectar.
