This amazing Texas native should be grown in every garden from Zone 7 south, and in containers from Zone 7 north. Resembling a rhizomatous perennial ageratum, this great native begins to flower in September and continues into December. The 3' wide slowly spreading mound of cutleaf light green foliage is literally smothered in fall with delightful 2" clusters of airy blue-violet flowers (RHS 92A). We would not be without this great native perennial in the fall garden
