Ilex glabra ''Shamrock'
Shamrock Inkberry is a relative newcomer to the Inkberry Holly list of cultivars. It was originally discovered back in 1977 among a large group of seedlings by John Tankard, Tankard Nursery, Virginia. Shamrock is a very nice compact inkberry with very lustrous dark green leaves - new growth being a much brighter, glistening green then maturing to the lustrous dark green color. This cultivar is now receiving serious attention from gardeners, designers, and landscapers across the country as it has shown itself to hold its leaves on the lower branches better than most inkberry. With maturity, produces large amounts of dark purple to black colored berries - production really increases after the third year of growth.
This plant is very useful as accent plantings, as well as for a maintained low growing hedge.
