Botanical Name: Magnolia ×loebneri ‘White Rose’

White Rose Loebner Magnolia
Campus: Kendal

Notable Feature: A selection offering exceptional cold hardiness and featuring heavily textured, pure white flowers with a rose-like form. Bred and introduced in 1988 by W.J. Siedl of Manitowoc, Wisconsin.

Habit: A small and rounded, deciduous tree reaching 15 to 20’ tall and 10 to 15’ wide. More often grown as a multi-trunked form than as a single-trunked tree. A cold hardy cultivar for Zones 4-8.

Foliage: The deciduous dark green leaves are a lighter green beneath; narrowly elliptic in shape, 4 to 6” long and 1 to 2” wide with a rounded apex and smooth margins. Fall foliage color is bronze.

Flower: Sweetly fragrant, pure white blossoms with 22 heavily textured, upright, petal-like tepals. Occasionally blushed with purple on the midrib and base of each tepal. Blooms are 2 to 2 ½” across and 1 ½” high. Blooming in April, flower form is suggestive of a gardenia or rose.

Fruit: Cone-like fruits ripen to red in late summer, releasing individual, red-coated seeds at maturity. Fruits are sometimes absent on this hybrid.

Interesting Fact: Magnolia ×loebneri is the result of a cross between two Japanese magnolias, Kobus Magnolia (Magnolia kobus) and the Star Magnolia (Magnolia stellata) made by Garteninspektor Max Löbner of Pillnitz, Germany, shortly after World War I. This cross has produced a diversity of plant habits as well as an early flowering trait that occurs into their second or third year of growth.
