The Story
Plant Bio
Ilex glabra, or Inkberry Holly, is a broadleaf evergreen shrub native to the eastern U.S. It is valued as a native alternative to boxwood, with spineless, glossy green leaves and an adaptable nature. GEM BOX® ('Ilexfarrowtracey') is a superior dwarf cultivar that maintains a dense, rounded, ball-like shape without pruning. Its small leaves emerge with attractive red tips in spring before maturing to a deep green, offering extra seasonal interest.
