About this plant
This is May-flowering when it charms with its pendulous flowers that are coloured green and white. The flowers have flared lips with slightly recurved petals and have a deep green line at the centre of each petal. They bear a distinct similarity to the appearance of white bluebells. The flowering stalk is curious in that it is three-sided, and stands around 30 cm high. This enjoys a part-shaded woodland site, which is where it grows in its Southern European homeland.

Autumn · 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.
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 during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
