This hybrid between M. kobus and the allied M. stellata was described from plants raised from a deliberate cross between the two species made by Max Löbner of Pillnitz, Germany, shortly before World War I. The original plants were sold in 1923 and of these Messrs Kordes of Sparrieshoop acquired five (Wilhelm Kordes in Deutsche Baumschule, August 1964, p. 242). Herr Kordes states in the article cited that one of the original plants, growing in his garden, is 25 ft high and 28 ft across, and produces flowers in unbelievable profusion about one week before M. × soulangiana. He adds that it is easily reproduced by cuttings.
M. × loebneri has typically about twelve petals to the flower and narrowly obovate leaves.
M. kobus var. loebneri (Kache) Spongberg
Some of the original seedlings were bought by Messrs Hillier, one of which was selected for propagation under the name ‘Snowdrift’.
