The Loebner magnolia (Magnolia x loebneri), is a hybrid of the Magnolia kobus and the Magnolia stellata. The tree usually develops as a multi-trunk small tree with a large crown. In the early spring, flower buds appear from velvety casings on bare branches. The long, narrow petals open first as a goblet shape and then as star shaped flowers. The flowers are fragrant. The tree has oval leaves turning yellow in the fall.Genus name honors Pierre Magnol, French botanist (1638 – 1715) and the epithet recognizes the German horticulturist, Max Loebner who made the first cross of this hybrid in the early 1900s. Magnolia x loebneri is the result of a cross between M. kobus and M. stellata made by Max Lobner of Pillnitz Germany.
