From Latin divarico meaning "spread out"
Some Native American groups of the Pacific Northwest foraged the berries. The bark and other parts had medicinal uses. The first published description of this species was by David Douglas in 1830.
Fruit is purplish-black (when ripe), subglobose (nearly round), and glabrous (hairless). Each fruit is 6 - 12mm in diameter.
Growth habit is of a shrub. It is perennial and deciduous, becoming dormant in winter but with persistent woody stems above ground.
Flowering occurs in April. The plant is hermaphrodite (has both male and female organs), and is self-fertile (one plant will fruit by itself). It is insect pollinated. Seeds ripen between July to August.
USDA Hardiness Zone 4 - 8. Hardy to about -20°c
Tolerance range is 4.8 - 8.2.
Tolerates moderate shade (approximately 20% shade / 1-2 hours of direct sun).
Hardwood cuttings (i.e. from fully matured stems) can be taken in late autumn (during dormancy).
The shrub can send out suckers, which can be propagated by carefully digging out the root and cutting it from the main plant.
From seed, greatest chance of success is as soon as ripe in autumn, using a cold frame.
The plant is moderately easy to care for.
Low water requirements.
May require pruning to keep from spreading.
Birds may eat the fruit.
Berries start green and turn black when ripe. Berries can be harvested before they are fully ripe assuming they will be cooked. Berries can be left hanging on the bush until Autumn, but birds may eat them.
- Fruit - fruits are edible by humans
- Hedging - large thorns can make this plant suitable in hedges to deter animals, such as deer.
- Bee plant - attracts bees and other insect pollinators.
- Attracts other wildlife - e.g. butterflies and brids.
- Cultivation of crosses and hybrids - e.g. R. divaricatum was used in the creation of the "Jostaberry" plant.W
