The Thimbleberry (Rubus parviflorus) is a prolific shrub along roads, in clearings, and logging slashes in Coastal BC.
Thimbleberry is in the rose family like blackberries and raspberries. Thimbleberry plants grow in dense thickets up to 2.5 metres tall, rapidly spreading from underground rhizomes. The large green palmate shaped leaves are fuzzy and have five points. Unlike the other berries, the canes do not have thorns.
The flowers are white with five petals and yellow stamens. They have the distinction of being the largest of any plants in the Rubus genus.
The berries ripen to a bright red in mid to late summer. Their shape resembles a thimble, leading to the plant's common name. Thimbleberries are a favourite with forest animals and birds.
Pick thimbleberries when they are bright red and juicy. They can be eaten raw, but because they have many small seeds they may best made into jelly or jam. -- Margy
