- Description
-
Cucumber Tree is a native deciduous tree found in eastern North America and is found in the foothills and Appalachian Mountains of NC. The tree is found naturally in subxeric forests (especially over rock) and in moist to dry slopes. It will grow 60-80 feet tall with a pyramidal crown and a straight trunk. The trunk diameter can reach 3-4 feet.
This is a deciduous magnolia that produces 2-4 inch slightly-fragrant, greenish-yellow, tulip-like flowers at the twig tips in late spring, but is named for the green, warty, cucumber-shaped fruits that follow the flowers. The leaves have nice yellow-gold fall color. Cone-like fruits mature to a showy red in late summer, releasing individual red coated seeds suspended on slender threads at maturity.
This plant tolerates a wide range of pH and prefers moist well-drained soil with organic matter in full sun to partial shade. It is sensitive to heat and drought, and has a low soil compaction tolerance.
These trees cast dense shade, and are beautifully symmetrical making them a park, residential and golf course tree of preference.
Insects, Diseases, or Other Plant Problems: No serious insect or disease problems. Magnolia scale is a potential problem.
