Fast growing evergreen tree or large shrub. A good form with feathery, divided, grey-green leaves and prolific clusters of scented bright yellow flower heads from late winter into spring.
Best in mild climate areas. Well drained soil in sun, drought tolerant once established. Can be slow to flower and may be cut back to ground in hard winters, but will usually re-grow quickly.
If required, prune after flowering. Can be pruned to make more tree-like or open. Alternatively the leader can be pruned out to create a more bushy habit. Remove any dead branches, which can be caused by excessive shade.
Good for cut flowers
