Aconitum columbianum Monkshood

It took me some time to identify this Oregon flower as most of the pictures on the web show the more common purplish-blue form. This white coloured variety is apparently much less common. I am indebted to Mark Turner of pnwflowers.com for help with this determination.

This plant was at approximately 4,500 feet elevation in open woodland south of Tollbooth, Oregon. The image has been cropped, resized and sharpened for TN. As it was taken in cloudy conditions, I have also brightened the image a little.


Blooms: June - August
Habit: herb
Duration: perennial
Origin: Native
Distribution: Alaska to California, east to Montana and New Mexico
Habitat: Moist woods and meadows, moderate to subalpine elevations

Species Description:

General: Stout, erect perennial from a tuberous crown, the several stems 5-20 dm. tall, glabrous below and pubescent above.
Leaves: Leaves alternate, cauline, long-petiolate below, becoming nearly sessile above; blades extremely
variable, 5-20 cm. broad, palmately deeply 5-lobed, the segments obovate to oblanceolate, incised to toothed to nearly entire; bulblets often developed in the leaf axils.
Flowers: Inflorescence a simple or branched raceme; pedicels slender, ascending; sepals 5, deep blue-purple or occasionally yellowish, the upper hood-like, 15-25 mm. high, the edges declined; lateral sepals obovate, up to 20 mm. long, lower sepals lanceolate, up to 15 mm. long; petals 2, concealed in the hood.
Fruit: Follicles 3-5, 10-20 mm. long.

Note: Toxic and can cause death if eaten.

Hello Alan,
In my stonegarden I have some blue Aconitum, but I never saw white ones. With this colour, they really look like monkshoods. Interesting posting, pleasant picture and interesting note. I see that the white species are as toxic as the blue ones. Very dangerous monks!!
Un grand merci
Have anice weekend

Bonjour Alan,
Le sujet est bien présenté mais manque légèrement de profondeur de champ.
A bientôt sur TN pour de nouvelles aventures.
