This hybrid arose c.1900 and commemorates Georg Arends of Ronsdorf,Germany.The hybrid name encompasses the hybrid products of A. chinensis var. davidii Franch. (which has purplish pink petals) and several other species, notably A. astilboides (a name of uncertain application in horticulture), A. japonica and A. thunbergii; all these hybrids have arisen since 1907.Original hybrids were by Lemoine of Nancy, France, and later Arends, who both attempted to explore the habits and colours of large and small species. Hybrids are extremely variable and there are now probably over
60 cultivars ranging in height from 60-120 cm and with flowers white to orange, pink, red and lilac, a few of which are available in Australia.
A. ×hybrida Ievinya & Lusinya encompasses a group of over 20 cultivars ranging in height from 0.6-1.8 cm and with flowers white, pink or purple. This group includes the cultivar 'Betsy Cuperus' which is a plant to over 1 m tall with flowers pale pink but otherwise similar to 'Professor van der Wielen', raised 1917, and 'Snowdrift', which has white flowers.
