A group of hybrids raised by Lemoine of Nancy around 1895-1900. All were put into commerce as ‘varieties’ of D. gracilis, which was one of the parents, the other being D. purpurascens. The first of the set (‘Rosea’), which Rehder took as the type, has ovate-lanceolate to ovate-oblong leaves about 2 in. long, which are more hairy than those of the first parent. Flowers in short broad panicles (not in elongated panicles as in the first parent, nor in cymes as in the second); petals pink on the outside, paler within. It makes a rather dense shrub, with arching branches and grows to about 3 ft high.
cv. ‘Carminea’. – This is the best-known of the group and one of the most delightful of dwarf deciduous shrubs. The flowers are pale rosy pink within, darker on the reverse and in bud, about 3⁄4 in. across, borne in May-June in large panicles. It makes a rather spreading plant, with arching branches, to about 3 ft high. Put into commerce in 1900.
Several other forms of the cross were distributed but are less common in gardens. ‘Campanulata’ is an erect, bushy shrub with large, white, rather bell-shaped flowers, with purple stalks and calyces. ‘Eximea’ is near to D. gracilis; flowers white within, pink on the reverse and bright pink in bud; leaves dark, bronzy green.
The form of D. × rosea figured in Bot. Mag., n.s., t. 189, is of uncertain identity, but near to ‘Carminea’.
