Seeds Bulk 1 oz. Thimbleberry

1 oz.  Rubus parviflora . Perennial. Zones 2 - 7. These shrubs reach up to six foot in height and bear lush, red, multi-seeded, bowl-shaped fruits. The plants thrive in moist shady areas. This deciduous shrub often forms thickets. The bark is flaky or peeling, but without prickles so common with many of the Rosaceae.  Approximately 7,000 seeds.

Thimbleberry leaves are large, 5-lobed; both surfaces – front and back – have soft hairs. The margins of the leaves are finely toothed. The small flowers, which bloom between May and August, have of five large white crinkled petals.

Although a nitrogen-demanding species, Thimbleberry grows well on a variety of barren infertile soil types. Tolerates a wide range of soil temperature and pH but requires adequate soil moisture for good growth. Grows well on dry, rocky soil and deep well-drained loam. Growth best on loam or clay-loam, fair on sandy loams, but poor on gravel, sand, or clay. Grows well on soils derived from a variety of parent materials. The plants can be started from seeds. Seeds have a hard, impermeable endocarp and dormant embryo. Consequently, germination is often slow. Warm stratify at 68 º to 86 º F for 90 days, followed by cold stratification at 36º to 41º F for an additional 90 days. Plant the seeds in individual pots in fine fertile soil. Keep well watered. Transplant seedlings when they are five to six inches tall.
