Alchornea davidii surprises with salmon pink leaves
Alchornea davidii, a new plant, is introduced in Europe. This stunning shrub or small tree is likely to have a promising future.
Alchornea davidii Leaves
In springtime Alchornea davidii (synonym: Alchornea trewioides) is a really stunning plant in your garden. In May it sprouts with a flush of leaves you will certainly remember: young leaves are bright salmon pink to soft flamingo pink! Looking from beneath the leaves look a little bit translucent.
Salmon pink is a highly desired colour in my garden. In the plant kingdom you don’t find this color very often. Just like vivid lemon green and fresh lemon yellow, which I also find very attractive. Because these hues are so rare and appealing, they always draws people’s attention.
On the internet you can find many pictures of Alchornea davidii with a flaming reddish pink colour in spring. The colour of the leaves is probably influenced by local conditions. I assume spring colour is soft pink in semi-shade, and a deeper reddish pink in full sun. Large temperature differences between day and night may also deepen leaf colour in springtime.
As the season progresses the leaves of Alchornea davidii turn green in summer. In autumn the leaves can get tints of yellow and red, depending on wheather conditions.

Applications of Alchornea davidii
In small gardens it is advisable to use a bamboo root barrier, made of a thick PE film. This will contain rampant root growth and prevents unwanted spread by underground root suckers.
I think in The Netherlands Alchornea davidii also stands out on roadside slopes along the highway, as a colourful alternative to Amelanchier lamarckii. It would make a drive along the highway a breathtaking experience!
Alchornea davidii & climbing Clematis
Spring Interest with Alchornea

Summer interest with Clematis
Clematis flowers offer summer interest.
Strong support
Alchornea branches provide support.
- Early in spring Clematis sprouts with vigorous shoots; these shoots need support to grow upwards. Alchornea forms sturdy upright branches that provide a solid support for Clematis. Long leaf petioles of Alchornea add additional support.
- Alchornea grows about 150-200 cm tall, which is a perfect height for most climbing Clematis.
- Clematis leaves start to unfold quite late, so they don’t distract from the pink Alchornea in spring.
- Branches of Alchornea hardly form side branches. This makes Clematis stems easy to remove during cleanup.
Green leaves in summer
Alchornea leaves turn green in summer. Clematis flowers, in whatever colour, benefit from a green background of another plant. By the time Clematis starts to flower the large leaves of Alchornea have turned green, thus the Clematis flowers show off nicely against the green Alchornea.
Be aware Clematis is a highly variable genus, divided into five different (pruning) groups. Take notice of these groups before buying a Clematis. Personally I would recommend using a Clematis of pruning group 3, such as Clematis Jackmannii and Clematis viticella hybrids. For a personal advice about cultivar choise you can send me an email.
Tip: In case you use a root barrier for Alchornea davidii, plant the Clematis outside the root barrier, with the base of the Clematis in the shade (north side) of its companion plant.
