Beautiful, low maintenance native plant that is unfazed by Tallahassee's floods and droughts. Makes a wonderful edging plant. Even when not in bloom, has fresh, light green foliage that is attractive.

When in bloom, this plant produces large numbers of blue or white flowers. It will bloom continuously for many days. They form nice, neat little clumps and are useful as border plants in the garden. They will tolerate some dry spells but do best with regular waterings.
