About this plant
This makes a low growing mound of slender grey green foliage that are carried on rather wiry stems. It comes into flower from April through to June, covering itself in good sized round faced white flowers that make open cups with yellow hearts. This is an excellent plant to grow in crevices in rock gardens, or even to colonize cracks in paving. This stands around 5cm (2in) in height and will spread to around 30cm (12in)

Spring
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
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.
