Cornus capitata (Bentham's Cornel)


Michael's Opinion

Bentham`s Cornel is an attractive border shrub, feature plant or woodland garden plant that can reach a height of 20 m in ideal conditions. Its creamy white bracts are stunning May through July and its red berries are eye catching in autumn through the winter months. This tree can create a mess in your garden as it is self-seeding and may become weed-like as the seeds are spread naturally and by feeding birds and small animals.

LandscapeCornus capitata can be used as a border shrub or as a feature tree in large gardens. The fruit attracts birds and small animals but it also creates a large amount of litter, so do not plant Bentham’s Cornel near high traffic areas.
PropagationIt can be propagated from seed or cuttings. Seed is best sown when the fruit is ripe in autumn, the fruit flesh must be fully separated from the seed as it contains germination inhibitors. The seed requires several months in a cool temperature to germinate, producing flowers in 8-10 years. Cuttings are taken from softwood immediately after first bloom in spring. Dip the cuttings into 1,000-3,000 IBA talc rooting hormone and place in a well drained soil. Cover the cuttings and keep moist and humid while roots develop; about 4-6 weeks.
CultivationBentham’s Cornel is an easily grown plant that succeeds in most conditions, adaptable to many soil types including loamy, sand, clay and peat. Preferring a pH range of 5-7 and partial shade to full sun.
PestsCornus capitata may suffer from Coral spot and Honey Fungus. Coral Spot can be pruned out while Honey Fungus has no remedy. Cornus capitata appears to be resistant to Cornus anthracnose, a disease that is common in other Cornus species.
