About this plant
This has attractive heads of lose packed pink-purple or white flowers, individually small but making irregular clusters or domes at the top of the upright stems. The individual blooms are starry with five petals, a darker eye and long wavy stamens. The plant has sturdy pearl grey stems that are velvety to the touch and horizontally held, and outward arching soft green leaves that are long and somewhat lance-shaped. These also have a velvety texture.

Spring
Spring-Summer · Indoors
Feed with houseplant food
Use a balanced house plant feed that has been diluted so it is half strength. Feed the plant monthly with this from May until August.
Where food elements are listed as three numeric values on the label representing in order Nitrogen(N)-Phosphorus(P)-Potassium(K), with percentage values for each, choose one where the values are more or less equal.
Spring-Autumn · Indoors
Water regularly during growth
Water regularly while in growth
Adopt a regime whereby plants are thoroughly watered every week so that they do not become dessicated. In hot weather watering may need to be more frequent, but less often in cool or moist conditions.
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
Prune after flowering
Remove any dead or damaged branches, or any growth that looks very untidy. Trim the plant back if necessary to keep it within bounds.
Winter
Winter · Indoors
Water moderately in winter
Water moderately.
Give a small amount of water so that the plant doesn't become flaccid (leaves lose their firmness and may droop or look lifeless), or dessicated, but do not saturate the compost or leave it standing in water.
Planting & general
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.
