Rubus parviflorus
Rubus parviflorus is a dense shrub up to 2.5 meters (8 feet) tall with canes no more than 1.5 centimeters (1⁄2 inch) in diameter, often growing in large clumps which spread through the plant's underground rhizome.[7][3] The plant produces edible composite fruit approximately 1 cm (1⁄2 in) in diameter, which ripen to a bright red in mid to late summer.The drupelets may be carefully removed intact, separately from the core, when picked, leaving a hollow fruit which bears a resemblance to a thimble, perhaps giving the plant its name.[9] Rubus parviflorus is native to western North America from Alaska south as far as California, New Mexico, Chihuahua, and San Luis Potosí.Thimbleberry is found in forest understories with typical flora associates including coastal woodfern (Dryopteris arguta), Trillium ovatum and Smilacina racemosa.
