Predominantly distributed in northern and northeastern China and the Korean Peninsula, Bunge based his description of W. florida on plants he observed in gardens in Beijing. Robert Fortune first saw it, also in gardens, on the island of Chusan, and purchased a plant from a Shanghai nursery which he sent to the Horticultural Society in 1844 (Bean 1981b). Bean quotes Fortune’s later recollections of this introduction and it seems appropriate to maintain this in full:
‘Revisiting the nursery some years later he was asked by the nurseryman and his sons how this and the other plants he bought had thrived. “I told them that most of the plants had arrived safely in England, that they had been greatly admired, and that the beautiful Weigela had even attracted the notice of her Majesty the Queen. All these statements, more particularly the last, seemed to give them great pleasure; and they doubtless fancied the Weigela of more value ever afterwards.” (Fortune, Gard. Chron., 1850, p. 757)’ (Bean 1981b).
W. florida was one of the commonest representatives of the genus in cultivation following its introduction, and it has been extensively used in the creation of new hybrids. Many cultivars have traditionally been attributed to this species but, for reasons discussed in the generic article, it is more prudent nowadays to follow the modern use of Cultivar Groups. In the Bean supplement (Clarke 1988) the authors appear to assign the collection ‘B. E. & C. 206’ to W. florida, however they also quote the very same collection in reference to W. subsessilis. Whether this is a misidentification, later corrected, from the field, or else an editorial error, remains unclear.
W. praecox is maintained as a distinct species in the Korean floras, however both the Floras of China and Japan syonymise this with W. florida (Yang et al. 2011). Historically, the separation could be justified from a horticultural point of view in the West as many early flowering hybrids were attributed to W. praecox, however the establishment of modern Cultivar Groups negates this argument and we have reduced it to syonymy.
Diervilla florida var. venusta Rehd.
Weigela venusta (Rehd.) Stapf
Differs from Weigela florida in that it has smaller obovate leaves that are glabrous.
RHS Hardiness Rating: H5
Taxonomic note This variety does not appear to be recognised by Korean floras.
A graceful shrub to 6 or 9 ft high, differing from the typical state in its smaller, obovate leaves. Corolla narrowing rather more gradually towards the base. Introduced to the Arnold Arboretum by J.G. Jack in 1905 from Korea, of which it is a native. Plants cultivated in the United Kingdom probably all derive from the seeds collected by Wilson in Korea in 1918. Bot. Mag., t. 9080.
