 Distribution

Eastern Canada and New England, south to GA, west to the Dakotas and south to OK.

Morphology

Woody perennial. Stems erect or arching, glaucous the first year, with stout straight or hooked prickles with an expanded base, the stems sometimes rooting at the tip. Leaves pinnately compound; leaflets usually 3 but sometimes 5, gray-tomentose beneath, the upper deeply serrate. Flowers white, 3-7 in an umbelliform cyme. Fruit red turning to black when ripe, occasionally yellow, with white tomentum between the drupelets, separating from the receptacle at maturity.

Notes

Flowers early May to late June

Wetland indicator: Upland

One of the best wild fruits. The berries are rather tart fresh but with a little added sugar can be used in any recipe that calls for raspberries or blackberries. The best time to pick them is usually early July. Hybrids with R. idaeus are called R. neglectus Peck.
