Rosaceae (Rose Family)

Synonym(s):

USDA Symbol: RUOD

USDA Native Status: L48 (N), CAN (N)

A suckering shrub, 3-6 ft. high and 6-12 ft. wide which forms broad patches. Five-lobed, maple-like, dark green leaves become pale yellow in fall. Large, pinkish-purple flowers occur singly or in few-flowered clusters. Fruit is a broadly rounded, red to purple berry. Canes are thornless, yellow- to orange-brown, and exfoliating. This erect, shrubby, thornless plant has rose-lavender flowers in loose clusters; new branches have bristly hairs.

Thimbleberry (R. parviflorus), with very similar white flowers and similar but smaller leaves, occurs from Alaska to Mexico and northeast to Ontario. Baked-apple Berry (R. chamaemorus), is a dwarf form only 12" (30 cm) tall, with a solitary white flower, an amber-colored berry, and leaves similar to the above, but smaller. It is found on mountaintops in New England and northward into Canada. All other species in the East have compound leaves and usually spiny stems.

Propagation

Description: Information about propagation by seed or cuttings is scarce because plants are so easily obtained by digging up suckers.
Seed Collection: Rubus fruits should be collected as soon as ripe to prevent losses to birds. The seeds can be extracted by macerating in water.
Seed Treatment: The hard, impermeable seed coat needs scarification. Both H2SO4 and sodium hypochlorite have been used. Scarification is sometimes followed by a complex combination of warm and cold stratification.
Commercially Avail: yes
