Magnificent deciduous garden shrubs, a little sensitive to frost when grown in dry soil, but nevertheless very effective.
The shrubs do not grow very large and their shape can be kept compact by correct; they are therefore very suitable for small gardens. For profuse flowering, full sun or very light shade is essential. The branches are cut right back immediately after flowering.
Will grow in any reasonable garden soil, but they will flower more profusely in heavy, rich soil.
