Culture
Best grown in medium moisture, well-drained, acidic loams in full sun. Adapts to a wide range of soils. Established trees have some drought tolerance. Although some flowers may be lost, it is best to prune this tree as needed in late winter. Spring pruning should be avoided as it produces fresh, open cuts where fireblight bacterium can enter.
Noteworthy Characteristics
Malus is a genus of about 35 species of deciduous trees and shrubs from Europe, Asia and North America.
Genus name from Latin is an ancient name for apple.
'Purple Prince' is a cross of (Malus ‘Bluebeard’ by Malus ‘Liset’) by Malus ‘Garnet’ that was developed by John L. Fiala of Medina, Ohio. The patent has been assigned to the J. Frank Schmidt & Son Co. nursery of Boring, Oregon. ‘Purple Prince’ is a small rounded tree with upward spreading branches that grows 18 to 20 ft. tall and wide. In spring, it has ovate purple-bronze leaves that gradually turn green in summer and then golden in fall. Its rosy red single flowers mature into round 3/8 to 1/2 in. purple fruits that persist into winter and attract birds. ‘Purple Prince’ has excellent resistance to scab and cedar apple rust and good resistance to fireblight and mildew. It is considered to be a rapid grower but is less likely to have problems with stem splitting. U.S. Plant Patent #8,478 issued November 30, 1993.
Problems
The main diseases of crabapple are scab, fire blight, rusts, leaf spot and powdery mildew. Potential insect pests are of lesser concern and include tent caterpillars, aphids, Japanese beetles, borers and scale. Spider mites may occur.
'Purple Prince' has good disease resistance to the main diseases of crabapples. | Amelanchier × grandiflora 'Autumn Brilliance'
Shrub form
Amelanchier x grandiflora is a hybrid cross between two species of North American serviceberry, namely, A. arborea (downy serviceberry) and A. laevis (Allegheny serviceberry). It is known in commerce today by several showy cultivars. This is a small, deciduous, usually multi-trunked understory tree or tall shrub which typically matures to 15-20’ tall. Flowers bloom in April followed by edible fruits (3/8" diameter) in June (hence the sometimes-used common name of Juneberry for amelanchiers). Berries resemble blueberries in taste and may be used in jams, jellies and pies. Finely-toothed, oval-lanceolate leaves (to 3" long) emerge with bronze tints in spring, mature to dark green from late spring throughout summer before finally turning brilliant red to orange-red in fall.

| Quercus bicolor
Swamp White Oak
Quercus bicolor, commonly called Swamp White Oak, is a medium sized, deciduous tree with a broad, rounded crown and a short trunk which typically grows at a moderate rate to a height of 50-60' (sometimes larger). Leaves are dark, shiny green above and silvery white beneath, with 5-10 rounded lobes or blunt teeth along the margins. Fall color is yellow, but sometimes reddish purple. Insignificant flowers in separate male and female catkins in spring. Fruits are acorns which mature in early fall. Indigenous to north, central, and eastern Missouri in moist to swampy locations in bottomlands and lowlands, such as along streams and lakes, valleys, floodplains and at the edge of swamps. Also has surprisingly good drought resistance.

Tolerate: Wet Soil | Firefall™ Maple
Acer x freemanii 'Firefall'
Firefall™ has an upright-oval form with good branch angles. This selection is male and therefore does not produce nuisance seeds. The foliage is an attractive medium green throughout the summer. Fall color is bright orange to scarlet and develops fairly early. This is a distinct advantage over some existing Freeman maple cultivars that color later and often do not develop much color in northern regions before freezing temperatures cause the foliage tomdrop.

| Sienna Glen Maple
Acer x freemanii 'Sienna'
The Sienna Glen Maple tree is a naturally occurring hybrid found on an abandoned farmstead in Lake Elmo, Minnesota. Its distinct, upright, pyramidal growth habit, which is readily apparent as a young tree, grows and becomes a broad pyramid when mature. The Sienna Glen exhibits vigorous growth yet withstands strong winds. The branches are borne more closely together along the trunk (than those of Autumn Blaze) and are finer and more delicate, yet the wood is harder and shorter and exhibit less drooping. The smaller, fine textured green leaves are dark green with a silvery underside and turn a variable mix of yellow and orange with a pinkish tinge at the highest part of the crown. As the fall color finishes, it turns a burnt orange. This beauty tolerates higher soil pH unlike Autumn Blaze, not exhibiting any chlorosis. Hardiness zone 4 (testing done in zone 3). Mature growth is around 60' tall x 40' wide.
