Plant in a warm, sunny, and sheltered position, ideally against a south- or west-facing wall for extra protection. Choose light, free-draining, slightly acidic soil and avoid heavy or waterlogged ground. Water regularly during dry periods while the plant establishes, but do not allow roots to sit in soggy soil.

After flowering, lightly trim or prune back shoots to maintain a neat, balanced shape and encourage bushy new growth. Avoid hard pruning into old wood as it may not reshoot.

In colder regions or during severe frosts, protect the plant with a double layer of horticultural fleece and apply a thick mulch of well-rotted organic matter around the base to insulate the roots. Feed sparingly in spring with a balanced fertiliser to support healthy growth and flowering.
