The raceme is slender, 4-12 cm long, 2-3 mm wide, and the total pedicel is 0.5-2.5 cm long. It is born on the top of the young shoots of the year. It has a shallow terminal with dense spherical or ovate large panicles (after anthesis The flower branches stop growing, and the other growing branches are drawn from the lower part, which grow rapidly upwards); the bracts are subulate, tapering, straight, 1.15 mm long, as long as the pedicel or almost as long as the calyx; the pedicel is as long as or slightly longer than the calyx. Flowers 5 number, small; calyx is 0.7-0.9 mm long, sepal is ovate, 0.5-0.6 mm long, 0.4 mm wide, obtusely acuminate, margin narrowly membranous; petals obovate, obtuse, about 1.5 mm long, 0.5 mm wide, about 1 time longer than the calyx, lavender or pink, half curved outwards, early fall; the disc is 5-lobed, and sometimes 2 divided into 10 lobes; the stamens are 5, the filaments are slender, extending beyond the corolla, longer than the petals 2 times, the base of the filament becomes wider, and it grows on the top of 5 disc lobes. Occasionally, each disc lobe is 2 lobed, and the stamens are born between the disc lobes, the anthers are heart-shaped, without pointed protrusions; the ovary is thinly conical, Style 3; Capsules are thin, 1.8 mm long and 0.5 mm wide, more than 2 times higher than the calyx. Flowering period is from the first half of June to the first half of July.
