Magnolia sieboldii.  A summer blooming Magnolia.  Nodding cup-shaped (4-5”) white    flowers with a red throat from red stamens.  Flowers are fragrant and the bloom is May-June and sporadically thereafter.  Our  plants are an outstanding form from the Miller Arboretum in Seoul, Korea; hardy enough to grow in Wisconsin and Minnesota.  Handsome in leaf, and ideal 10-15 foot size.  A prize for that special spot in the garden.

Stewartia pseudocamilla  We have been growing this small (20-30’) tree with success for many years.  Late summer flowers look like camillas, white with an orange throat from orange anthers at the center.  This tree develops spectacular multi-colored exfoliating bark.  The fall colors are a mixture of yellow, red, and purple hues.  A superb small tree for a focal point in the garden.  This year we are going to try the exquisite small Stewartia sinensis with bark like polished marble.

Acer pseudosieboldianum  This small Korean maple is hardy to –40 degrees F. with bright yellow, red, and orange fall colors.  Grow in sun or shade, a great substitute for the marginally hardy Acer palmatum.

Acer triflorum  Another very hardy trifoliate Asian maple,  lovely foliage turning a rich yellow, red and orange in October, exquisite exfoliating bark, a real treasure,  about 20’.

Acer tschonoskii ssp. koreanum  An uncommon hardy small maple from the mountains of North Korea, young branches are bright red ; leaves have 3 prominent lobes with red petioles.  The fall color is a fiery red, as brilliant as any of our own sugar maples; to see this plant is to want it.

Carpinus caroliniana  A small understory native tree noted for its fluted bark; with smooth rounded ridges; a sinewy look giving rise to the name Musclewood.  Lustrous green leaves turn yellow-red-purple hues in the fall, quite wonderful. This tree usually grows with irregular wide-spreading branching ; an interesting architectural pattern.  Our trees are from a Wisconsin stand with very good fall color.

Cercidiphylum japonica  The Katsura Tree, will embellish and enhance any garden.  The heart-shaped leaves are a beautiful  red-purple in the spring, go to a bright green during the summer, and to apricot colors in the fall The tree has a charming compact habit.  It will get to 40’ or more and should be placed in full sun.

Cornus kousa The Chinese Dogwood, is another prize for that special spot in the shrub border or garden.  Rather spectacular white flower brachts cover the tree in May-June, followed by red raspberry-like fruits.  Bark becomes a mottled brown-gray with exfoliating strips.  Fall colors range from scarlet to red-purple.  The habit of the tree with horizontal branching is another great asset.  We also grow the pink flowered forms “Satomi” and the new “Radiant Rose”

Cornus florida  The Flowering Dogwood, known as the aristocrat of native American flowering trees, blooms earlier than the Chinese Dogwood, so the flower brachts are sometimes injured by late spring frosts.  The horizontal branching with a layered effect, the soft gray color of the branches, the consistent red-purple leaf colors in the fall make this an exceptional tree to consider.  Our form is from the northern race of Cornus florida, native to Allegan County in Michigan

Heptocodium miconiodes The Seven Sons’ Flower Tree  This unique small tree is covered with clusters of fragrant white flowers, the month of September when few trees are in bloom .  The calyx of the flower turns red and is even more ornamental the entire month of October.  For two months the tree lights up the garden.  The leaf is a lovely simple deep green and the bark an exfoliating gray-brown with light and dark hues, a nice asset year around.

Viburnum sieboldii `Wavecrest’ This cultivar is among the finest viburnums for the Midwest.  It has sharp clean foliage.  Leaves are large, deep green and lustrous.  In the fall the foliage turns a bright red-orange. Flowers heavily in May with clusters of white flowers on long stalks that become orange berries in August. The pedicels to the flowers are bright scarlet, and remain showy after the birds get the berries When grown on a single trunk,  this viburnum will reach 20’ and makes a wonderful three-season small tree. Viburnums are easy to grow and offer three season appeal; our favorite group of shrubs; over the years we have collected some 40 varieties that we offer in our plant list. In the words of Dr. Michael Dirr: “A garden without a viburnum is akin to life without music or art”
