About this plant
This has delicate flowers that appear from mid to late spring. The flowers are coloured a creamy white and have four long petals (technically called tepals) They are long and slender and open to reveal cream stamens at their heart. The flower bows its head and will nod in the breeze. It has pleasant leaves, slender and lance-shaped with toothy edges. This is tolerant of shaded positions and is also suitable for a container. It needs very good drainage to thrive. It should be pruned and tidied immediately after flowering has finished, otherwise, it is low maintenance.

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.

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.

Apply an organic mulch
Apply an organic mulch to the plant taking care not to bury its stem or cover any young growth that emerges from its centre.
A mulch is a covering that can: protect the soil surface from rain, heat and cold; deter weeds; provide nutrients. Organic indicates that material has vegetative origin e.g. manure, compost. Synthetics i.e. plastics, or stones are often called mulches.
