About this plant
A striking and exotic variant that has an arrangement of leaves like the spokes of an umbrella, long and slender, rich green with an impressed midrib. These are held atop a curving pale green stalk. The flower arises from the base on its own stalk. It has a deep tapering funnel-shaped flower, green and cream without, and with a dramatic maroon and green striped lip with extensive elongated tip. Red berries follow the flowers.

AutumnNow
Autumn - late · Outdoors
Apply a protective mulch
Protect the crown of the plant in winter in areas that are prone to frost and cold. For short term protection a fleece can be used, otherwise fill mesh sacks with masses of straw and secure them over the plant's crown.
The 'traditional method' is to put wire or other netting over the plant, layer plenty of straw on top of this and then secure the whole with more netting.
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.
Summer
Summer · Planting
Remove offsets to create new plants
Offsets are small plants or shoots that develop around the parent plant. They should have developed a root system of their own before they are detached. They can be planted directly, or grown in pots if so small they could be 'lost' in the garden.
Offsets may be used to replace an aged parent plant, to extend or establish a colony, or can be given away or sold.
