About this plant
This is a pretty and wide spreading tree which can be several times wider than it is high. It has very fine, ferny, divided foliage and fluffy, pink flowers which form in late summer and early autumn. The flowers have a perfume rather like that of sweet peas. Sometimes, flat seed pods follow, though they can look a bit messy when they drop on the ground. When it matures, the tree can look rather leggy and bare at the base but this is easily remedied by growing it behind low growing shrubs. It has an exotic, tropical look and is considered to be tender, but actually has a fair degree of hardiness. A fine cultivar of this tree grows and flowers in the Royal Botanic Gardens, Kew.

Spring
Spring - late · Outdoors
Feed young plants with slow release fertiliser
Spread a slow release fertiliser around the base of the plant to the edge of the foliage spread, so that it can feed the roots. It is helpful for this to be applied for several years.
This is a simple way to provide a nutrient boost until the plant becomes well established.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
Planting
Protect & support young trees
Attach a newly planted tree or tall shrub over 1m to a tree stake to give support and prevent windrock. Use a tree guard to stop tree bark being eaten by animals, especially in areas with deer - removing bark injures a tree and in worst case can kill it.
