Buddleja × wardii is a naturally occurring hybrid of Buddleja alternifolia and Buddleja crispa discovered and collected by Frank Kingdon-Ward in 1924 from the mountain riverbanks of south-eastern Xizang (formerly Tibet) at altitudes of 3000–3600 m; B. alternifolia and B. crispa are the only other Buddleja species found in the area. The shrub was named for Ward by Cecil Marquand in 1929.[1][2][3] White-flowering plants under this name were collected in Tibet by Keith Rushforth and introduced to commerce in the UK in 2013.[1]
