Pinus mugo ‘Mops’ is an excellent dwarf selection that grows into a low, dense dome remaining compact without shearing. The mounding plant has a smooth appearance that comes from many evenly spaced needles growing at a uniform rate on abundant branchlets. During most of the year, ‘Mops’ displays a hint of gray/blue in its green, but during the crisp, cold months of winter, needles take on a warm, golden hue. It’s no wonder this choice is one of our most popular for confined spaces.

Steel blue needles and horizontally layered branches make Picea pungens ‘Lundeby’s Dwarf’ a neat and reliable landscape conifer that becomes wider than tall with age. A rare form of Colorado Blue Spruce, it stays compact and provides an attractive mounding form that stays in scale, even in small urban and suburban gardens. Discovered by Lundeby Nursery in North Dakota, it is useful as part of a foundation planting, as a focal point or in a rock garden or container.

Thuja occidentalis ‘Zmatlik’ is medium green throughout spring and summer, but in winter, as temperatures fall, it puts on its winter coat of intense plum-bronze. The winter color is very dramatic and adds to the already interesting texture of this hardy narrow column. Small, scale-like sprays of foliage twist and curl creating a densely foliaged plant than can be enjoyed as a single specimen or planted as a screen. Found as a seedling by Mr. Zmatlik in the Czech Republic in 1984.

For longer needles, a more natural, open look and a consistent habit, the versatile Pinus mugo ‘Palouse’ is perfect for a casual landscape where a larger Mugo Pine is warranted. The robust green selection grows into a bushy, rounded mound, or with annual candle pruning, it can be kept smaller and more refined. A reliable and hardy addition to the sunny mixed border, it also works well as a divider or to fill a corner.

Pinus mugo ‘Palouse’

Winter is the season when Pinus mugo ‘Laarheide’ literally shines in the garden. Throughout the growing season it maintains as a low-key garden element with its medium green needles. As winter approaches, the needles turn color and become an outstanding luminous yellow that brings the winter garden to life. Growing wider than tall, ‘Laarheide’ provides a colorful addition to harsh winter climates.

Super hardy with a super form, Prairie Statesman^® will make an elegant statement under some of the harshest conditions. Soft, emerald green foliage, with a hint of silvery blue, adorns this perfectly symmetrical tree. Its columnar habit provides a narrow footprint making it suitable for the home garden as well as large landscapes. Drought tolerant and extremely cold hardy, it is an excellent selection by Dr. Dale Herman, North Dakota State University. Pinus cembra Prairie Statesman^® (‘Herman’)

Picea pungens Monty® (‘INMoHoop’ PP34,883)

Picea pungens ‘Montgomery’ is an outstanding and industry standard silver-blue spruce that was originally part of the conifers accumulated by dedicated collector, Col. R.H. Montgomery. Prior to selling his Greenwich, Connecticut, estate, he donated his entire collection to the New York Botanical Garden, and this Picea pungens was named to honor him during the dedication of the Montgomery Conifer Collection in May, 1949. The original plant can still be seen there today. The slow-growing, dwarf spruce is globe-shaped when young, but it will eventually form a leader as it matures and develop an upright, broad shape that is wider than tall.

Very short needles earned Picea pungens ‘Bonny Blue’ its name and fame. The tiny, narrow needles are bright blue and they are closely arranged with an angle that is acute to the stem. Slower growing than the species when young, the tree, selected by Roger Mackiness, Corbett, Oregon, matures into a large formal stature.

The Limey Norway Spruce

Formally thought to be a seedling selection of Picea glauca, the originator of this exciting plant has informed us that ‘The Limey’ is truly of Norway Spruce origin.Fresh, new foliage emerges each spring from the buds of Picea abies ‘The Limey’ with a bright lemon-lime color. Short needles adorn open branching that will fill in with maturity. As the season progresses, the exposed topsides of the needles remain a pleasant yellow while the undersides and shaded interior foliage turn lime green creating a striking contrast. ‘The Limey’ thrives in moist, well-drained soil.

Lanham’s Beehive Spruce

The late Gary Lanham found this unusual, boldly textured, compact Norway Spruce in 1994 in Kentucky, a witch’s broom nearly 10′ up in a mature Picea abies. Intrigued by the interesting beehive form, Gary took it to Klein’s Nursery in Louisville, and from there, it made its way to Iseli Nursery. The needles of Picea abies ‘Lanham’s Beehive’ are longer and thicker than other dwarf cultivars and they have a slight glaucous tint. These features, combined with prominent, cinnamon colored stems and buds, create a dramatic effect.

The compact, spreading Larix kaempferi ‘Wolterdingen’ provides exceptional seasonal interest for small landscapes and rock gardens. In early spring, soft, new, blue-green needles emerge and continue to decorate the delicate mound through the growing season. In fall, needles change to rich yellow before they fall to show off ornamental, reddish brown branches with scales reminiscent of an armadillo’s armor. Discovered in a park in Wolterdingen, Germany in 1970, by G. Horstmann.

Varied Directions Larch

This name could be an understatement! In fact, the vigorous, spreading habit of this Larix decidua ‘Varied Directions’ produces robust twigs that propel the branches up and out, in—that’s right—varied directions. Golden tan branches, covered with thick twigs, eventually arch down and cover the ground in a unique configuration for each plant. Bright green spring foliage changes to gold in autumn before needles fall. Selected by Dr. Sydney Waxman, University of Connecticut.

Acer x pseudosieboldianum Ice Dragon^® is a welcome addition to the Jack Frost^® collection of hardy garden maples from Iseli Nursery. This all-season tree has a cascading habit and was bred and selected to tolerate Zone 4 winters while still retaining the refined qualities of the less hardy Japanese maples. Spring begins as leaves unfurl blushed orange-red, quickly maturing to green. In summer, the finely divided, delicate appearing green leaves are durable and tolerant of sun and heat. Autumn brings foliage of a kaleidoscope of yellow, orange and red. After leaf drop, the sinuous and undulating branching structure is a visual treat during the long cold winter months.

Three Assorted unique dwarf conifers & two  perennials selected for our Northern Climate create unique patio bowls that, with proper overwintering can remain outdoors year round.

Larix decidua ‘Puli’ is an elegant alternative to the common L.d. ‘Pendula’. When staked, its slender branches create a narrow silhouette that is more dense and lighter green than ‘Pendula’. If unstaked, ‘Puli’ branches spread out slowly along the ground and make an effective ground-cover. Very attractive in gardens with an Asian aesthetic.

The compact, bushy Ginkgo biloba ‘Mariken’ was discovered in 1995 as a witch’s broom growing in a Ginkgo tree in the Netherlands. It has proven an excellent find, descended with the unique history of the species, with the same fan-shaped green leaves that turn bright yellow in fall. But ‘Mariken’ stays very small, its thick, spreading branches loaded with a dense arrangement of foliage. The slow-growing, deciduous conifer makes a high-interest architectural feature, a flat, rounded, form, for either small garden or container.
