Rubus parviflorus 

Snow Bramble

In the rose family. Medium to tall shrub, 1-2.5 m tall, from extensive rhizomes, often thicket-forming; stems erect to ascending, fine-hairy and stalked-glandular, becoming smooth eventually; bark grey, flaking-off. Leaves alternate, deciduous, long-stalked, mapleleaf-shaped. Produces hairy, raspberry like berries. 

Moist to mesic open forests, thickets, streambanks, clearings and roadsides in the lowland to subalpine zones. Occurs on nitrogen-rich soils within boreal, temperate, and mesothermal climates; its occurrence decreases with increasing elevation and latitude and increases with increasing continentality. Very common in open-canopy forests and early-seral com­munities on cutover and/ or burnt sites where it may hinder natural regeneration and growth of shade-intolerant conifers.
