The fruits are bluish white. White dogwood is used to form bushy groups on lawns or bordering paths. If the climate is Mediterranean, it can be grown in semi-shady understory. It's suitable for large pots on terraces and patios. Cornus alba can be grown in full sun exposure if the climate is cool-temperate; In regions with a Mediterranean climate, it should be placed in semi-shade. It resists cold and frost. Siberian dogwood can grow in any soil that contains organic matter. Transplantation or planting is done in early spring.

Prune intensively in early spring. Cornus alba is a plant quite resistant to pests and diseases; you just have to watch that they have the appropriate humidity. Red-barked dogwood propagates by seeds sown in spring in a protected seedbed, by cuttings or by division. |
