About this plant
A tree that is stunning when in flower. It produces bright pink frothy sprays of bloom, white at their base. These stand proud on top of the spreading branches and look exotic and improbable. The tree makes a broadly spreading fan with long slender twigs that carry finely divided, tiny, pinnate (paired) leaflets. The leaflets actually close up during the evening. The branches stretch out widely from the main body of the tree and it needs a position that takes account of its wide-spreading habit when it has matured. The flowers are followed by long seed pods which are not especially ornamental. This exotic tree is comparatively hardy and should be given a sunny sheltered position.

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.
