Buddleja officinalis is a deciduous early-spring flowering shrub native to west Hubei, Sichuan, and Yunnan provinces in China.[1] Discovered in 1875 by Pavel Piasetski,[2] a surgeon in the Russian army, B. officinalis was named and described by Maximowicz in 1880. Introduced to western cultivation in 1908, B. officinalis was accorded the Royal Horticultural Society's Award of Merit three years later,[3] and the Award of Garden Merit (record 689) in 2002.[4]
Description
Buddleja officinalis largely resembles the commoner
Cultivation
Buddleja officinalis is not fully frost hardy, unable to survive temperatures lower than −10° C, and is best grown against a south-facing wall.[1] The shrub should be cut back hard each year immediately after flowering in spring. Propagation by softwood cuttings is easily accomplished, using vermiculite as a rooting medium.
