About this plant
Visitors to the Azores may see this growing as a tree though it is highly unlikely to achieve equivalent stature in the cold United Kingdom. It is a striking plant with great, though somewhat untidy, presence. One of those exuberant baggy guests who spread themselves everywhere. There are great whorled heads of luscious leaves, some tinged red purple, otherwise coloured apple green and having a pronounced white central rib. The leaves are borne on the current seasons stems so bareness develops if it survives the winter. Hard prune to overcome this! The flowers are coloured pale yellow and come during May and June. It is a tender plant though has survived the winter in Oxford Botanic garden. Its height in Britain is likely to be around 1.5m (5ft) with an equivalent spread. In the Azores it can be 10m (33ft) in height.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
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.
