Rubus odoratus
Rubus setosus
Rubus odoratus is introduced in Washington State. The species is distinguished from other flowering raspberries by its erect, unarmed stems, simple leaves, large flowers, magenta petals, glabrous, clavate styles, and purple stipitate glands densely covering most plant parts. A hybrid with R. nutkanus (R. ×fraseri Rehder) is thought to occur in areas of overlap in northern Michigan (E. G. Voss 1972–1996, vol. 2).
The Cherokee used leaf infusions for labor pains and the Iroquois used plant infusions for miscarriage (P. Bergner 1997). Rubus odoratus is grown as an ornamental for its relatively large flowers and magenta petals and its edible fruits that are somewhat dry and insipid.

Rubus setosus is identified by erect to arching, rarely creeping, not tip-rooting, terete primocanes, always setose but variable in density, and deciduous primocane leaves that are often palmately compound with five leaflets. Cultivated plants sometimes alternate from erect to creeping (or vice-versa) in successive years, depending on changing soil conditions.
