Looking like a Veronica on steroids, this large growing American Beauties perennial loves full sun and flowers like it's on steroids, too with an impressively long season of bloom to match its considerable size. This upright grower has whorled, lance-like leaves that unfurl on rapidly growing stems in the spring and are topped by long spires of buds by mid-May. These 9"+ long spires open with small white to pale blue flowers from top to bottom in late May and continue to bloom into mid summer on these spires and smaller side ones, attracting a considerable group of native butterflies throughout. Veronicastrum is impressive in stature and flower power and can make a big impact at the back of a garden and a big impact on your local garden critters.
