An upright, frost-tender, woody-based perennial to 90cm tall with small, aromatic, mid green leaves. Tubular, pink-purple flowers with darker calyces are borne in open racemes on dark stems over a long period- usually from early summer to late autumn.
Grow in humus-rich, well-drained soil in full sun or lightly dappled shade in a warm, sheltered position; protect from frosts by overwintering under glass or treat as an annual.
