This rather distinguished looking prostrate plant has quite large, oval leaves. The relatively large, cup-shaped flowers sit almost on the leaves. These are white, yellow tinted at the centre. It flowers profusely and the plant can be completely smothered in flower.

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 during dry periods
For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.
Summer
Summer · Planting
Trim the plant

Winter
Winter · Outdoors
Water lightly during dormancy
The soil should be kept just moist during the plant's rest period.
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.
Compost · Planting
Loam based compost + grit for repotting
Use a free draining loam based compost rather than one which has been modified to be 'moisture retentive'.
Alternatively prepare a compost using three parts of loam (John Innes no. 2 or 3) to one part of (horticultural) sand or fine (horticultural) grit.
