About
Disporum longistylum 'Green Giant' is a robust perennial that can reach heights of up to 3 meters under optimal conditions. This plant develops dense clumps of upright stems adorned with glossy, deeply veined leaves that are lance-shaped and may take on a purplish hue in their youthful stage. In late spring and early summer, it produces small clusters of drooping, pale yellow-green flowers, characterized by their extended styles and stamens. As autumn approaches, these flowers give way to berries that mature to a dark black color.
