Arizona bugbane is an herbaceous perennial that reaches 3-6 feet in height. It has large, long-petioled lower leaves and small sessile upper leaves. The toothed leaf blades are divided into three leaflets. This species produces rather showy white flowers that grow on long stalks and bloom in slender clusters of small, petal-less flowers. The seeds resemble furry little bugs. (Phillips et al. 1996)
This is a rare plant that has very narrow habitat restrictions. It exists in only four small population areas in Arizona, and is not Federally protected. Major problems facing this species include an apparent lack of genetic variation as well as extremely poor germination rates in cultivation, which hinders attempts to grow individuals for reintroduction programs. (DeWald & Phillips 1996)
Distribution & Occurrence
Often found in the transition zone between coniferous forest and riparian habitat at elevations of 5300 to 8300 feet (1829 to 2529 meters). This species is often found near perennial or intermittent streams, and appears to prefer locations with high humidity and moist, rich, fertile soils. (DeWald & Phillips 1996; Phillips et al. 1996)
|Found in four population areas in Arizona (DeWald and Phillips 1996).|
Conservation, Ecology & Research
Flowers are pollinated by three bumblebee species, with peak flowering times (early August) coinciding with peak population abundance of the bumblebees. (DeWald & Phillips 1996)
