Cucumber Tree, Cucumber Tree Magnolia
Magnolia acuminata

Description

Magnolia acuminata, or cucumber tree magnolia, is native and endangered in Ontario and thrives in moist, organically rich, well-drained loams with full sun to part shade. The native range of the cucumber tree extends across eastern North America, from southern Ontario and western New York southward to Georgia and westward to Arkansas. It is sensitive to soil extremes and urban pollutants, making it best suited for parks or large lawns rather than urban streets. While it can be messy due to its large leaves, flowers, and long cucumber-like seeds, it is a valuable addition to landscapes.
