About this plant
Delightful low growing, spreading plants with masses of pretty flowers in every shade but blue and purple. They need well drained soil and sunshine to thrive. At their best in raised beds or tumbling over rocks. They are also attractive as mounded features in gravel gardens. There are green and grey foliage forms. They are summer flowering and the flowers, produced in masses though each individual bloom lasts only a day, always appear fresh and clear.

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 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.
Planting & general
Planting
Prune young growth after flowering
When the plant has finished flowering, remove the flower and most of the young growth that the plant has made. Leave just around 2 centimetres of young growth on the plant. Don't cut into old wood unless it is diseased or damaged.
