aka Columbian Monkshood. Don’t let the innocence of the clerical reference fool you, this plant is very poisonous; containing aconitin, an ester alkaloid that paralyses the nerves. The showy deep blue-purple flowers are fairly large, 1 -2″ (up to 5 cm) with a hood-like, or helmet-like, upper part. The stems can reach 7′ in height. Somewhat rare in the Park and may be difficult to spot since it grows amongst dense vegetation. Usually found in moist places at forest edge in the upper forest zone and lower subalpine zone, elevation 3,500′ – 6,000′.
