  • Other features: beautiful conservatory tree if lightly trimmed after flowering has finished

Fluffy yellow, sweetly scented ball-shaped flowers cover the ends of the branches from winter to spring. An evergreen tree with a pale green trunk and large feathery glaucous leaves. It makes an ideal conservatory plant or in warmer gardens can be planted in a sheltered spot against a south-facing wall. It will never reach the magnitude of those in its native Australia but it can grow to 12m (40ft) in 20 years so it does need plenty of room in the garden.

  • Garden care: Lightly prune after flowering has finished, cutting back shoots that spoil the shape of the tree. In the garden incorporate lots of well-rotted garden compost into the planting hole and stake firmly. To grow in a pot, plant in a loam-based potting compost and keep in a sunny spot.
