About Cornus controversa Variegata
The variegated layered dogwood is a spectacular appearance that is among the most beautiful variegated trees. This cultivar of the layered dogwood is distinguished by its horizontal branch structure and creamy-white mottled leaves. Its growth form is highly architectural: the branches grow in clear, horizontal layers one above the other, creating a stepped, layered crown. This unique growth habit gives the tree an Asian look reminiscent of a pagoda.
The trunk is straight and strong, with a smooth, grey bark that has little texture when young. The branches branch in a regular pattern and spread horizontally, each level being slightly narrower than the one below. This symmetrical structure makes the tree highly recognisable and decorative.
The leaves are the most striking feature: each leaf has a broad, irregular creamy white to creamy white margin around a green centre. Some leaves are almost completely white, while others have a narrower margin. This varied pattern creates a pale, almost white crown visible from afar. The leaves are elliptical with distinct veins. In spring, the young leaves appear with a pink tinge, especially at the edges. In autumn, the leaves turn purplish red to pinkish red, with the variegated parts often taking on pink hues.
Flowering occurs in May-June with small, creamy-white flowers arranged in umbels. The flowers contrast nicely with the mottled leaves. After flowering, small, blue-black berries develop, which are eaten by birds but inedible to humans.
The variegated layered dogwood grows slowly to moderately fast and remains more limited in size than the green-leaved species, usually to 4-6 metres. The tree requires good, moist soil and does not tolerate drought. Its spectacular appearance and architectural form make this an excellent solitary tree for a prominent spot in the garden. It is a plant that demands space and attention, and more than repays that with its unique appearance.
Application and location
The variegated layered dogwood requires a prominent location as a solitary specimen where its architectural shape and mottled leaves are shown to their full advantage. This tree is suitable for spacious gardens, parks and business parks where it acts as an eye-catcher. Give it enough space and preferably surround it with lower plants so that its layered structure is clearly visible.
Plant the tree in semi-shade to light shade. Too much sun can cause leaf burn on the white leaf parts, while too much shade will cause less variegated leaves. The soil should be nutrient-rich, humus-rich and above all moisture-holding. This dogwood does not tolerate drought and grows best in moist to wet soil without permanent waterlogging. A slightly acidic to neutral soil is preferred. Hardy to about -20°C, but cold winds can damage the leaves so some shelter is favourable.
Give the tree ample development space: at least 8-10 metres in diameter. Pruning is basically not necessary and usually undesirable as it disturbs the natural shape. At most, remove dead wood. Note that this tree grows very slowly, so be patient. Provide regular fertilisation and plenty of water, especially in dry periods. With proper care, this is a spectacular sight that gets more beautiful every year.
