Magnolia × loebneri (Paul Kache)[1] is a hybrid of two Magnolia species, the Japanese Magnolia kobus and M. stellata.[2] crossed by Garteninspektor Max Löbner of Pillnitz, Germany, shortly before World War l;[3] it first flowered in 1917.[4] The deciduous, elegant[5] and compact multi-stemmed small flowering tree or large shrub, slowly attaining a height of 20 feet and somewhat wider at maturity, is hardy to USDA Zone 4.[6] 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.
The selection, 'Leonard Messel' was a chance hybrid that was developed at Messel's garden in Sussex, Nymans. Also on the market are white 'Ballerina' and the late-flowering white 'Merrill' that extend the loebneri season.
