Cultivation
Prefers a good well-drained slightly acid loam but succeeds in dry soils, growing and fruiting well so long as the canopy of pines is fairly light. Although it is very winter-hardy, this species only really thrives in areas with hot summers. This species is a natural hybrid, C. dentata x C. pumila. Flowers are produced on wood of the current year's growth. Fruits are produced in 2 - 3 years from seed. This species is occasionally cultivated for its edible seed in N. America, there are some named varieties. Plants in this genus are notably resistant to honey fungus.
Propagation
Seed - where possible sow the seed as soon as it is ripe in a cold frame or in a seed bed outdoors. The seed must be protected from mice and squirrels. The seed has a short viability and must not be allowed to become dry. It can be stored in a cool place, such as the salad compartment of a fridge, for a few months if it is kept moist, but check regularly for signs of germination. The seed should germinate in late winter or early spring. If sown in an outdoor seedbed, the plants can be left in situ for 1 - 2 years before planting them out in their permanent positions. If grown in pots, the plants can be put out into their permanent positions in the summer or autumn, making sure to give them some protection from the cold in their first winter[K]. This species is a natural hybrid and might not breed true from seed[K]. Division of suckers in winter. They can be planted straight out into their permanent positions.
