A moderately tall, upright plant, with sturdy stems and dark green leaves. Does not require staking. Deep blue, helmet-shaped flowers develop on panicles in fall. Plants and blooms will power through light frosts into November. All parts of this plant contain the alkaloid toxin aconitine, which makes this plant exceedingly deer-resistant. Our plants are sited in part shade under trees, where they seem to compete well with tree roots for moisture. Plants will slowly spread to cover an area over several seasons. Our plants are frequently attacked by Verticillium wilt, which causes stunting and mangling of tip growth late in fall.
