About this plant
This good looking climber has pendulous, heart-shaped leaves and, in the summer, clusters of white flowers that look a bit like the down folding petals of half an enormous chrysanthemum. This is a very different and interesting climber that likes a sunny to part shaded site. If you are patient, it can climb through a large tree but you have to wait a few years before you will see any dramatic flowering results.

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.
Winter
Winter - late · Planting
Prune to maintain the plant
Remove and dead or damaged branches or any growth that looks very untidy. Trim the plant back if necessary to keep it within bounds.
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.
