Purple flowers up to 15cm (6 in) from April to June. Prefers well drained soil in full sun. It can hump up to 20cm (8'') high, but to maintain optimal appearance it needs to be shorn back to within 5cm (2'') of the ground after it has finished blooming late in spring or early summer. This will induce fresh leaf growth with perfect colour & density, and should induce summer rebloom. |
