Shamrock Inkberry
Ilex glabra ‘Shamrock’ · a compact inkberry holly
One of the most compact inkberries, a native evergreen with glossy, deep green leaves, a boxwood alternative for foundations, low hedges and massing. It takes wet spots and salt spray, and its black berries feed birds if a male is nearby. It drops its lower leaves with age; cut it back hard now and then to renew it.
