What is Inkberry (Ilex glabra)?
Inkberry, or Ilex glabra, is a species of evergreen shrub native to eastern North America. It is a member of the holly family, Aquifoliaceae, and is commonly found in wetlands, swamps, and coastal areas.

While these berries may not be palatable to humans, they are a valuable food source for birds, adding ecological value to the landscape. Inkberry typically grows in a mounded or upright manner and can reach a height and spread of 6 to 8 feet, making it suitable for a variety of garden settings.
