Remove faded leaves as and when they appear tatty, and prune lightly in mid to late spring, trimming shoots that spoil the symmetry. Protect plants from cold, drying winds and avoid poorly-drained ground conditions likely to become waterlogged in winter. Plants may need protection when temperatures start to dip in colder regions. Provide a deep mulch over winter in colder areas. If kept frost-free it will be evergreen; with mild frosts the plant is deciduous, and in colder areas it may die back to ground level then reshoot from the roots. Remove suckers if you want to prevent the spread of established clumps.
