Rubus odoratus
Rubus niveus
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 niveus is distinguished from other raspberries by its pinnately compound leaves with 5–7 leaflets, ovate to broadly ovate terminal leaflet, leaflets with prickles on the midvein, and pink to magenta, broadly obovate to orbiculate petals. The species was introduced into southern Florida around 1949 from seeds obtained in Kenya and quickly became popular for its fruits, which are edible fresh or frozen and are often used in preserves, pies, and tarts (J. F. Morton 1987).
