Korean Sweetheart Tree

Bright Red Fruits of Sweetheart Tree

The late Dr. J. C. Raulston, N.C. State University horticulture professor emeritus, discovered Korean sweetheart tree in 1985 on the Korean Peninsula while participating in a U.S. National Arboretum collection expedition. 

Dr. Raulston brought seeds back to the N.C. State Arboretum for assessment and evaluation. The common name "sweetheart tree" was coined by Tennessee nurseryman Mr. Don Shadow.

The tree prefers a sandy or medium loamy soil and full sun to partial shade. Once established the tree tolerates brief dry periods lasting 4-5 weeks, and is at its best in soils with consistent and even moisture. Provide supplemental irrigation in regions where summers are exceptionally hot and dry.

Opposite pinnately compound leaves measure 6-10 inches long. The fruits are major asset for this small growing tree/large tree. In late summer showy clusters of heart-shaped fruits ripen from green to pink to red. In early to mid-October the fruit capsules split open to reveal a tiny, shiny, black seed.The grayish colored bark has white striations which adds some winter interest.

No serious disease and insect problems trouble this small 25-30 feet tall tree. Availability is primarily from on-line plant nurseries
