Yellowhorn Xanthoceras sorbifolium

Yellowhorn is a rare, deciduous shrub or small tree in the maple family (Sapindaceae) native to Northern China. It will grow in a variety of soil types, but prefers loamy soil, in a sunny, warm and dry location.  This plant will perform at its best in a location that experiences dry springs and warm summers. It needs to be protected from frost and cold winds, as a late spring frost can damage the young growth. To stimulate the production of flower buds, summer heat is required. That heat will help to fully ripen the wood and stimulate flower buds.  

Its spring-blooming white flowers bloom with white edges and yellow throats. As the flower mature, the throat will turn to a deep maroon color. Plant as a specimen or in small groups, in a border back, or near a patio. Blooming takes place on old wood, so pruning should be accomplished after the spring bloom period.  

The flowers, foliage and seeds are edible. The flowers and leaves are usually boiled. The seed which is about the same size as a pea has a sweet taste, will remind you of a sweet chestnut. The seed is husked and ground into a powder, then boiled.

An excellent choice for a small landscape, where light pruning can control the tree size.  

Its native habitat includes rocky slopes on hills and mountains.

Insects Diseases, and Other Plant Problems:  Coral spot fungus can occur, particularly when the wood is not fully ripened and the plant is exposed to a late frost.
