  form2 form Form

-large shrub or small multi-trunked ornamental tree

-maturing slowly to 15' tall x 15' wide

-upright oval growth habit in youth, becoming spreading and mounding

-slow growth rate

foliage Foliage

-medium to dark green, deciduous, alternate, distinctly obovate, to 4" long

-autumn color is green to yellowish green in Nov.

Flowers
flowers

-winter floral buds are prominent and fuzzy, giving rise to showy flowers that have narrow petals and sepals (tepals) that are white (sometimes light pink or rose) and slightly fragrant, and emerge in Apr. before the foliage

-in Ohio, flowers are frequently browned or killed by early spring frosts and freezes, and may remain attached to the plant until mid-spring

-may sporadically have a very few flowers open anytime from late summer to late autumn, but this does not affect spring flowering

Fruit

-sparse aggregate fruits split open in Sept., but are not ornamental and seldom produced in significant quantities

Twig
twig

-gray-brown, with prominent leaf scars, exhibiting distinctive sympodial branching

-terminal floral and vegetative buds are densely and noticeably pubescent (fuzzy), and are much larger than the lateral buds

-stems are more dense but much thinner as compared to those of Magnolia xsoulangiana (Saucer Magnolia) and other Hybrid Magnolias, and buds are not quite as large (especially the floral buds)

trunk Trunk

-multi-trunked, with bark that is light gray to gray-white and smooth, with the trunks sometimes allowed to remained branched to the ground, even at maturity

Culture

-full sun to partial shade

-performs best in partial sun in moist, acidic, deep soils but is quite adaptable to a wide range of soils, soil pHs, pollution, and even wet soils

-virtually no disease or pest problems, although sapsuckers may encircle the trunk on occasion with small holes

-commonly available, primarily in B&B but also in container form

Hardiness

-zones 4 to 8

Origin

-native to Japan

Assets

-outstanding floral display in a frost-free early Apr., with flowers slightly fragrant

-flowers at a young age

-fuzzy winter terminal buds

-subtlely ornamental smooth gray bark (if limbed up into tree form)

-can be utilized as a deciduous privacy screen near foundations due to its dense summer foliage

Liabilities

-frost often kills the emerging flowers

-temperatures below -10 degrees F or harsh winter winds may actually kill the floral buds, long before they are due to emerge

Function

-foundation, specimen, entranceway, or spring accent large shrub or small tree

Texture

-medium texture in foliage and when bare

-thick density in foliage and when bare
