Blooming This Week (second week of September, 2012):

Vernonia lettermannii ‘Iron Butterfly’

This dwarf threadleaf selection of Ironweed was introduced fairly recently to the gardening public, coming to us via renowned plantsman Allan Armitage of Georgia. Although its parentage is native to southern states ‘Iron Butterfly’ has proven itself fully winter hardy here for us. In fact Richard Hawke, plant evaluation manager at the Chicago Botanic trial gardens, says it is one of the most noteworthy of recently trialed plants there.  Here at Monches Farm we love it, too!

Its thread-like foliage is borne on upright stems that form a compact mound reminiscent of another favorite, Amsonia hubrichtii (Threadleaf Bluestar ). In late summer the flower buds form on well branched heads atop the 24”-36” stems. Rich purple flowers open in autumn and provide a welcome late season nectar source for butterflies, who visit this plant in abundance.

‘Iron Butterfly’ is tolerant of a wide range of soil types and has shown itself to be particularly drought tolerant. It prefers full sun and is hardy Zones 4 – 9.
