Genus

Rubus

The Rubus genus in the Plotwright catalog — 4 species: Allegheny blackberry, American red raspberry, Blackberry, Flowering raspberry. Open any for hardiness, native range, wildlife value, and growing guidance.
Rubus allegheniensis
Allegheny blackberry
A native eastern + central North American thicket-forming shrub producing arching thorny canes + clusters of large sweet black berries in mid-to-late summer. Among the most important wildlife fruit producers in eastern forests — birds, mammals, + insects all depend on the fruit. Like raspberry, biennial-caned (primocane year 1, fruits in year 2 as floricane, then dies back). Spreads via root suckers + tip-rooting cane tips; manage with annual pruning.

Rubus idaeus
American red raspberry
A native bramble (cane) producing red aromatic edible fruit in summer or fall (depending on summer-bearing vs everbearing cultivar). Self-pollinating; spreads vigorously by root suckers + tip-rooting canes. NC State documents extensive Lepidoptera + small mammal + bird wildlife value alongside the edible fruit role. Site where the spreading habit is welcome — naturalized colonies form in sun-exposed open ground.

Rubus fruticosus
Blackberry
The familiar European blackberry, a vigorous arching thorny deciduous bramble that forms dense thickets and bears clusters of large sweet black aggregate berries in mid-to-late summer. Rubus fruticosus is not a single plant but a species AGGREGATE of many closely related microspecies, long cultivated for its fruit. HONEST CAUTION: while the berries are edible and excellent, the European blackberry aggregate is a load-bearing INVASIVE in many temperate regions. It and the closely related Himalayan blackberry (Rubus armeniacus) escape gardens into dense, impenetrable, thorny thickets that smother native vegetation, and are serious noxious weeds across the Pacific Northwest and elsewhere. Where it is invasive, plant a regionally-appropriate native bramble (Plotwright carries the native Allegheny blackberry, Rubus allegheniensis) or a sterile/thornless cultivated cultivar instead.

Rubus odoratus
Flowering raspberry
A thornless native bramble grown for its flowers, not its fruit. Large, fragrant rose-purple to magenta blooms open over a long stretch of summer above big, soft, maple-like leaves on bristly (but prickle-free) canes. Native to the woodland edges and rocky slopes of eastern North America, it suckers into loose colonies 3-6 feet tall and is one of the few shade-tolerant, showy-flowered shrubs in the genus Rubus. The flat red aggregate fruit that follows is edible but dry and seedy — most gardeners grow this plant for the bloom and the unarmed, handsome foliage.
