Vernonia angustifolia

Common Name(s):
Tall Ironweed
Categories:
Native Plants, Perennials, Wildflowers
Comment:

A native wildflower in the Asteraceae family is easy to grow in the full sun.  It is mostly seen in natural landscapes, and will tolerate periodic flooding and wet soils, but it preforms in cultivated garden soils as well.  Showy magenta purple flowers appear in the summer and are attractive to butterflies.  The plant reproduces and grows easily from seed so deadhead flowers to prevent unwanted reseeding.  This plant hybridizes with other ironweeds which can make identification tricky.  Reduce plant height by cutting back stems in late spring.  Works well in a naturalized landscape, cottage garden, as a backround plant in a boarder or in a rain garden.
