|This is a deciduous shrub with slender arching branches and a compact and bushy growth habit. It is a cross between Spirea cantoniensis and Spirea trilobata. Leaves are obovate, scalloped, toothed, dark green with a blue green underside, to 2 inches long, occasionally lobed at the tips. Small, white cup shaped flowers are held in dense corymbs to 2 inches across, along shoots from June to July. This shrub can grow in either acid or alkaline soils and though it prefers moisture, can withstand some drought.
