Overview of Indian hemp, Apocynum cannabinum. Considered by some sources to be invasive or weedy, the flowers are delicate and pretty. The common name comes from its use as fiber by prehistoric peoples (Whitson et al. 2002). Photo taken on 15 July 2004 on the Columbine Canyon to the Meadows Trail.

Close-up of leaves and stem of Indian hemp, Apocynum cannabinum. This species is very close in appearance to Apocynum androsaemifolium, but red stems are what caused me to label this as Apocynum cannabinum. Photo taken on 15 July 2004 on the Columbine Canyon to the Meadows Trail.
