‘Chesapeake’ Japanese Holly has a compact, upright, pyramidal shape, with small lustrous evergreen foliage. The dense habit makes Ilex ‘Chesapeake’ an excellent candidate for a neat short hedge which requires little pruning to maintain its shape. Similar in shape to Ilex ‘Steeds’, ‘Chesapeake’ also works well as a formal foundation plant.
'Green Lustre' Japanese Holly has shiny small green leaves and has a flat-topped shrub habit, making it excellent for low hedges. It does well at the seashore because it is salt tolerant. Evergreen and a female form introduced in the 1930s.
'Helleri' Japanese Holly is evergreen with tiny green leaves. on a dwarf, stiffly mounding plant. Our landscaper friend Martin Blackman says this is the only Japanese Holly he can use with success in deer-infested Princeton. A female introduced in the late 1930s by Newport Nursery.
'Hoogendorn' Japanese Holly has dark green delicate evergreen leaves on a low mounding habit. It is more graceful looking than Ilex c. 'Helleri' and has gotten high praise from Dr. Michael Dirr as one of the best of the small-leaf Japanese Hollies. It was found on Hoogendorn Nursery in Rhode Island, so it's clearly cold tolerant. This male form of Japanese Holly was found at Hoogendown Nursery and named by T. Dodd.
'Sky Pencil' Japanese Holly has a very upright columnar form and glossy evergreen foliage. It looks like an exclamation point in the landscape. It is also salt tolerant. Ilex crenata 'Sky Pencil' needs some babysitting after snowfall to avoid bending branches. A female form found in Japan and introduced by the US National Arboretum and W. Steeds.

Proven Winners® Color Choice® Gem Box® ('SMNIGAB17') Inkberry Holly is an exciting alternative to Boxwoods. The habit is round and full to the ground, without the bare branch look which many Ilex glabras exhibit as they age. As Boxwood Blight becomes more of a regional problem, this tough native evergreen shrub will become more important for containers, low hedges and small round garden specimens. New growth is spring has reddish tips which mature to small dark green leaves.
'Shamrock' Inkberry is a compact upright form of Ilex glabra with small glossy leaves. It is wet site tolerant and great for evergreen hedges. A female form named and introduced in 1977 by John Tankard of Tankard Nurseries in Virginia.
Strongbox® ('Ilexfarrowtracey') Inkberry Holly is a welcome introduction from Proven Winners offering a good native substitute for Boxwoods. Ilex glabra Strongbox® looks like a short round Buxus, but it is more sun tolerant and moisture tolerant., as well an unthreatened by Boxwood Blight. Since this compact Inkberry stays full to the ground, it can be used in containers, for low hedges and in mass plantings. The tight habit and small leaves make pruning rarely necessary.
'Maryland Dwarf' American Holly is a very unusual female form of our wonderful native evergreen Holly. It slowly forms a very wide mound, with dark green minimally spiny leaves and some red fruit production. American Hollies are amazingly versatile in the North East, thriving from sunny swampy areas to dry shade locations, so 'Maryland Dwarf' can be used in a number of different locations.

Its growth habit is an upright vigorous pyramid, so it makes an excellent specimen as well as a good choice for hedging. Introduced by S. McLean.
Male Longstalk Holly is the proper pollinator for our female selection. In order to get the best fruit set possible, use at least 1 male for every 5 females. We originally received our Ilex pedunculosa seed from the Arnold Arboretum, which introduced this beautiful Holly to the US in 1892.
'Chrysocarpa' Winterberry has bright yellow fruit which lasts well into the winter (birds prefer to eat red fruit). Its deciduous leaves drop somewhat earlier than most red-fruited varieties, so that the fruit is visible early in the fall. The pollinator is I. 'Jim Dandy'. Like all Winterberries, it is wet site tolerant.
PRN Preferred: The best yellow fruited Winterberry we grow.
Jim Dandy' Winterberry is the early blooming pollinator for Ilex verticillata 'Afterglow', 'Chrysocarpa', 'Goldfinch', 'Maryland Beauty', 'Red Sprite' and 'Stoplight'. Deciduous.
