Where temperatures are mild, lion's tails are perennials. In cold-winter places, they may die back a bit, but sprout new growth again in spring. At the end of winter cut it back to around 20 centimeters to promote new spring growth. Moderately drought tolerant once established and a nectar source for birds and butterflies. To prevent garden escapees, avoid planting near disturbed bushland or coastal reserves, regularly prune seed heads and dispose of garden waste responsibly.
