You could drive a truck over this long-lived awesome perennial without doing more harm than breaking a few branches. Tough as nails and long-lived, it’s heat and drought tolerant, deer and snail resistant. Want more? Okay, lots of bright truest royal blue “Forget-Me-Not” flowers display for months on sturdy multi-branching stems. When it’s finished, cut it back to the foliage for a second performance as good as the first! Not fussy about soil but a yearly addition of compost gets a fantastic result. Popular with swallowtails! Grows to 4’ tall by 3’ wide.
