The small lustrous green leaves and stems are topped by showy flat white flower clumps in April and May. Iberis sempervirens 'Snowflake' has a cascading habit, so it is a good choice for mixed containers or short walls.
‘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.
'Steeds' Japanese Holly has an upright pyramidal form with dark green glossy evergreen foliage, excellent for hedging. Ilex crenata 'Steeds' is also salt tolerant. A male form, named and introduced by W. Steeds.

Dark green leathery leaves of Ilex glabra 'Densa' are rounder and wider than I. g. 'Shamrock'. It will become a tall but dense-leafed shrub. Takes pruning well. Evergreen, it is also wet site and salt tolerant. The top performer in the recent shrub trials at Longwood Gardens. A female form found by our cousin Bert Flemer in 1938 at F&F Nurseries in NJ.
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. It was introduced by in 1942 by E. Dilatush from Bunting Nursery. Definitely an unusual, groundcover shrub.
PRN Preferred: Definitely an unusual groundcover shrub which we love because of its diversity.
'Satyr Hill' American Holly is considered by the American Holly Society to be one of the best female forms, for both foliage and fruit. The dark olive-green leaves are somewhat flatter than most opacas, and 'Satyr Hill' produces abundant red fruit from early October through the winter. 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.

Red Beauty® ('Rutzan') Holly is another introduction from Dr. Elwin Orton's lifelong work with the genus Ilex. The shiny dark green leaves are spiny, neat and small, covering its conical, pyramidal form. It is readily pollinated by Ilex x meserveae males, and the fruit is attractive on its evergreen setting all winter. Slow growing and narrow, it fits in well in smaller garden spaces. Most exciting of all, it has proved to be extremely deer resistant according to Bruce Crawford of The Rutgers Gardens.
PRN Preferred: Doesn't require a specific pollinator to produce red fruit. Perfect size for smaller gardens.
Dragon Lady® ('Meschick') Holly is a very glossy, upright female plant, with an excellent fall and winter display of bright red fruit. Ilex x aquipernyi Dragon Lady® was hybridized by Kathleen Meserve. Evergreen and does not need a pollinator. Ilex 'Dragon Lady' has proved to be very resistant to deer browse.
'Woodland Ruby' Anise-tree has deep purple-red straplike flowers for an extended period in early to mid summer. Foliage is dark green and evergreen, somewhat reflexed in winter. Illicium x 'Woodland Ruby' needs protection from winter winds and is happiest in some shade, but will tolerate full sun as well. Per Bruce Crawford, it is happy in both wet and dry shade sites (as are many flood plain plants).
Chinese Indigo has clear pink flowers on slender racemes which are produced from June through the summer. Indigofera decora stays low but gets wide, because of its suckering habit. The flower display looks like short pink Wisteria blossoms. Try it on walls, where you can see flowers more easily.

'Moonlight Waves' Japanese Iris blooms in June producing large flat white flowers with lime and yellow centers ('signals'). The strap-like green leaves are clean and dramatic all summer. When in bloom, Iris 'Moonlight Waves' looks like floating handkerchiefs above sword-like foliage. This is a favored plant in the famous "White Garden" of Sissinghurst in England.
'Rose Queen' Japanese Iris produces white and rose pink flowers in June in a somewhat more pendant form than most ensatas. The "falls" are white with dark pink veins and the "standards" are pink with a deep rose base. The narrow upright blades are attractive all summer. Deer resistant and wet site tolerant, 'Rose Queen' looks a little more "naturalistic" than most Iris ensatas.
'Best Bet' German Bearded Iris produces tall spikes of large flowers with blue standards and purple falls. The two toned effect is very showy, blooming first in May and June, and then reblooming in September and October. The sword-like green foliage emerges before the flower spikes, and fades by late summer. Good drainage is a must for Iris germanica cultivars.
'Superstition' Bearded Iris has such a dark purple flower that it almost looks black. The blooms are fragrant and large, making a striking addition to cut flower arrangements (even though the individual flowers each last only a day). The flowers spikes bloom above the wide straplike leaves in May and June. All German Irises perform best in dry or well drained sites. Iris germanica 'Superstition' is the darkest flowering germanica.
'War Chief' German Bearded Iris blooms in May and June, producing lots of large velvety dark red flowers. They are held above wide straplike green foliage, and are a good addition in the back of well drained perennial beds. Iris germanica 'War Chief' is a useful and fragrant cut flower, since the stems have multiple buds that open in succession.
Bold Pretender Louisiana Iris has flat showy flowers in early to mid summer. The petals are a combination of pink and red, with striking yellow veining coming from the center. Louisiana Irises flourish in moist and wet sites, so ‘Bold Pretender’ is an excellent addition to pond and stream margins, where it can help prevent bank erosion.

Siberian Irises are very tolerant of a number of soil conditions, and are particularly attractive in rain gardens and around ponds.
Slippery Slope™ Chinese Roof Iris was found in Sichuan by Darrell Probst (of Coreopsis and Epimedium fame). He introduced it because of its size and vigor, as well as the beauty of its blue purple veined flowers. The centers (signals) of the largest petals are white with dark purple veining. The green leaf blades stay clean and attractive all summer, and Iris tectorum Slippery Slope™ expands to making low growing attractive groundcover. This is an Iris that works well as a green roof plant.
'Wolong' China Roof Iris has light lavender flowers flecked with purple spots above fans of wide green strap-like leaves. The foliage is somewhat floppy but lasts all summer, unlike its North American relative Iris cristata. The flowering period is late April to June. It comes from Sichuan, China from a collection made by Jim Waddick. 'Wolong' Roof Iris won the 2010 American Iris Society's Award of Merit. Try it as a slow spreading groundcover or on a green roof that gets adequate moisture.
White Japanese Roof Iris gets its name from its presence on thatched roofs in Japan. Iris tectorum var. album has large white flowers with yellow throats, appearing in late April to early June. All the Japanese Roof Irises spread to make wide patches eventually, and do best with adequate moisture but good drainage. It is the Asian equivalent of Iris cristata 'Alba', but much bigger and not ephemeral. A hard-to-find Iris.
