About this plant
This variety of the three leaved, three petalled, wake robin has delicate, silken, clean pink blooms, a colour that takes on deeper tones with age. The flowers, in April and May, look as exotic and ephemeral as a large, winged butterfly, complemented by three large, fat, glossy, dark green leaves on each stem.

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.
Spring · Planting
Divide after flowering
After flowering divide the rhizomes, this needs to be done with care as each part of the rhizome must have a growing bud point or it will fail. Dust the cut surface with fungicide before replanting.
Identifying a bud point: each rhizome has a large shoot at its growing point. Behind these are a number of small pointed buds that stick out between the rhizome's scales, pointing upwards.
