Planting

Choose a permanent position in sun or partial shade with well-drained soil. Check the eventual size of your selection: this species can develop a broad, tree-like outline.

Care

Prune lightly just after flowering, which occurs on the previous year's growth. Avoid removing thick branches or repeatedly trimming the shrub to fit a small space.

Before planting: Root disturbance and heavy pruning are poorly tolerated.
