| General Description | This subspecies has been placed on the IUCN Red List as least concern. |
| Propagation | Propagate either through fresh seed that is sown immediately, by older seed that has been chilled for three months before sowing in spring, or by simple layering. |
| Cultivation | Thrives in a loamy soil, and is also suited to a chalky substrate. Regular pruning can help control vigour, size, and colour quality. |
| Pests | May be attacked by multiple species of caterpillars, aphids, and powdery mildew (Phyllactinea corylea). Grey squirrels (Sciurus carolinensis) cause the greatest losses to nut collection, taking the nuts before they are ripe. |
