Gardeners' Notes:

Positive plant_it On Apr 29, 2013, plant_it from Valparaiso, IN wrote:

Beautiful plant native to North America (widely occurring east of the Mississippi River from Michigan to Maine and south to Georgia). Very showy late spring-early summer flowers are pale purplish-pink, snapdragon-like and on 2 to 4 foot tall spikes. The late-spring blooming period provides color during a period when most spring flowers are finished and summer blooming species have yet to open.

Attracts butterflies, not palatable to deer.

This is a good plant for naturalizing in moist to dryish places in part shade in neutral to basic soil as it has a tap root that will help it deal with drought.
