Columbian Monkshood

Aconitum columbianum

Columbian Monkshood (Aconitum columbianum) is a landscape plant valued for its form and structure as much as its bloom. It reaches roughly 5 ft at maturity and blooms in early summer. Match it to full sun to part shade and keep the root zone consistently moist. One caveat worth knowing before you plant: parts of this species carry a toxicity flag (moderate), so keep it away from pets and kids who chew on landscape plants. Given a spot that matches its light and water needs, it is a dependable, low-drama addition to the yard.
