Magnolia × loebneri Kache is a hybrid of two Magnolia species, the Japanese Magnolia kobus and M. stellata. crossed by Garteninspektor Max Löbner of Pillnitz, Germany, shortly before World War I; it first flowered in 1917. The deciduous, elegant and compact multi-stemmed small flowering tree or large shrub, slowly attaining a height of 20 ft (6.1 m) and somewhat wider at maturity, is hardy to USDA Zone 4. Its fragrant late flowers, following its stellata parent by a couple of weeks, escape unexpected late spring frosts, but appear on the bare branches, to great effect. The deep pink buds open in informal strap-like tepals with pale shell pink upper surfaces and darker pink-purple lower ones. Like most magnolias, it thrives best on acid soils.
