Rubus odoratus
Rubus phoenicolasius
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 phoenicolasius was introduced to North America for edible fruit, breeding stock, and for ornament. Attractive for its typically reddish purple glandular hairs, R. phoenicolasius nonetheless can be invasive.
