by the British explorer and plant collector E.H. Wilson. Wilson sent plant material to his sponsors Veitch Nurseries in Exeter in 1901, where the shrub flowered for the first time in 1910. The shrub became very popular in the eastern United States following World War I – almost a defining shrub in American gardens made between the World Wars. It is very rare and threatened in the wild.

Cultivation

Pruning

Opinions differ concerning how much pruning the shrub needs. The University of Missouri Horticulture Department suggests minimal intervention, so long as the plant has enough room to develop, up to a maximum height of and a potential "spread" of . Others suggest more active intervention to encourage development of new flowering branches and buds, with decisive pruning immediately after flowering.
