This shrub is deciduous so it will lose all its leaves in autumn, then fresh new foliage appears again each spring. This is a vigorous shrunb that likes a full sun position in a light, moderately-fertile, well-drained soil. It flowers from June to September and is fully hardy. Can grow up to 2m x 2m. If you have a corner to fill where you don't mind this taking over and giving year upon year of flowers its a great addition to any garden. Also great in a large border as a back drop to cottage perennials.
