Verbena bonariensis - Purpletop Vervain

Verbena bonariensis is a great perennial for the cut flower garden. This is a six foot tall perennial. Verbena bonariensis will attract bees and butterflies. I cut the plants nearly to the ground each winter. Rooted suckers and seedlings are fairly common but not too difficult to keep to reasonable numbers. Starting in mid to late spring through Fall there are numerous clusters of purple flowers. Some removal of the spent flowers will keep your Verbena bonariensis blooming continuously. The Giant Swallowtail, Gray Hairstreak, and Variable Checkerspot will come by for nectar if they are around.
