Dahoon Holly
Ilex cassine
Although drought tolerant once established, this 30 foot tree or shrub likes rich, moist soil along the edge of wetlands or lakes.
The berries which ripen in September and remain until December are not poisonous or tasty. Many birds and animals eat the fruit which can start out as yellow and end up red as in this picture.
Since this plant is dioecious, you will need to plant several in order to assure getting a male and female and thus berries.
Plant inland in rich acid soil with a combination of other wetland species. These may include: cypress, red maple, cocoplum, virginia willow, carolina willow, pond apple, swamp redbay, slash pine, laurel oak, marsh fern and bloodroot.
