Magnolia Seeds - Cucumber Tree

(Magnolia acuminata) Zones 4 - 8. Deciduous, flowering tree. Rare & Endangered.

The Cucumber Magnolia is native to Ontario's Niagara Region and is unfortunately on the cusp of extinction. Because of habitat loss (logging, farming, urban sprawl, etc), this once plentiful tree has been reduced to less than 200 regional individuals. They also do not fair well with prolonged dry spells, meaning changing weather patterns have also been a factor in their decline.

When established in an ideal environment, however, Cucumber Magnolias can get big, and quickly. It is one of the largest of the Magnolias! They have upright, yellowish flowers in the Spring which give way to curious cucumber-like seed pods. These start out green and change to a pinkish-red in Autumn.
