About this plant
This curious small tree is a cross between laburnum and cytisus. It is an attempt to realise the drama of purple and yellow blooms on the same plant. Superficially it looks like a laburnum but the outer branches look rather like its other half, the cytisus. It is in fact grafted, the technical term for it being a chimaera. Some of the flowers are the yellow columnar laburnum, others, more closely clustered on the branches, are coppery-pink. In specimens I have personally observed, the laburnum predominates. The tree seems happy with its lot in life, whether the customer feels he has got what they paid for is another matter. Give it a sheltered sunny or partly shaded site with deep well drained soil. It could reach 6m (20ft) height with a 4m (13ft) spread.

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 to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
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.
