About this plant
These are lively flowers that are basically white but with bold and variable purple coloration. This includes flashes of colour at the petal base and often having streaks of purple across the whole petal. There is some purple tinting at the petal edges. The single open-faced flowers have rich golden domes at their heart and have wavy, slightly irregular petals. In fact the whole bloom appears to be a delightful experiment! The flowers stand on sturdy stalks and should be a feature from July onwards, often going into autumn. These would be attractive grown in a container or could be interesting in the foreground of shrubs with red-purple foliage such as Physocarpus opulifolius Diablo D'Or = 'Mindia'.

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 - early-mid · Planting
Divide when too large
The plant can be divided if it becomes too large or another plant is required. This may involve physically dividing the clump in two, removing offsets or small bulbs or dividing rhizomes. The new plants can be grown in pots or planted in the ground.
Planting & general
Planting
Deadhead blooms during flowering season
Remove flowers as they turn brown and fade. Snip the stem just below the bloom. This will keep the plant tidy and encourage more flowers.
The removal of spent flowers encourages the plant to produce fresh ones, rather than spend its energy on the development of seeds.
