Cornus controversaWedding cake tree
The architecture of Cornus controversa is built from successive tiers of horizontal branches, forming a layered silhouette that remains recognisable even in winter. In early summer, each platform is covered in white flower heads, visually reinforcing the organisation of the crown.
- Horizontal branches arranged in superimposed tiers, creating a pagoda-like architecture
- Alternate leaves, an unusual arrangement within the genus Cornus
- White corymbs resting on the branches, followed by small dark blue fruits
About this species
Cornus controversa grows as a medium to large tree, usually reaching 6 to 10 metres in height and width. In favourable conditions, old specimens can approach 15 metres and form a crown as broad as it is tall.Read moreShow less
Cornus controversa grows as a medium to large tree, usually reaching 6 to 10 metres in height and width. In favourable conditions, old specimens can approach 15 metres and form a crown as broad as it is tall.
The main branches extend almost horizontally from the trunk and are organised in successive layers separated by visible gaps. This structure gives depth and rhythm to the crown, allowing each tier to be read individually. With age, the tree acquires a sculptural presence comparable to the architecture of a pagoda.
The broad, glossy leaves are arranged alternately on the branches, unlike the opposite foliage characteristic of most Cornus. In early summer, flat corymbs of up to around 15 centimetres appear, made up of numerous creamy-white true flowers, without the large bracts of Cornus kousa or C. florida. Dark blue fruits may follow, while the foliage takes on red and purple tones in autumn.
It prefers gentle sun or partial shade and a deep, fertile, moist, well-drained soil, acidic to neutral in reaction. A regular supply of water during growth favours the balanced spread of the branches, and it is important to allow space for the crown to develop its horizontal planes freely.
It is suited to use as a single tree in lawns, parks, large gardens and compositions where the silhouette can be seen from a distance. A mature specimen from Diaplant immediately brings the first tiers of branching already defined, bringing forward the architectural character that a young plant would take many years to build and making it possible to select a tree with proportions suited to the setting of the project.
