About this plant
This is a plant of curious charm that makes a dense mat of foliage. The slim, oblong leaves are rounded at their ends and when well-baked, are matt and silvery in effect. The neat rosettes of felty looking leaves are far finer in effect than the well known, silvery, groundcover plant Stachys byzantina. The pendulous, pretty flowers are made up of slim white tubes with pink tinges at the mouth.

Spring
Spring-Summer · Outdoors
Water during drought
Water plants in the ground regularly after a period of drought if still in growth (prefer to be dry when dormant). Check plants in pots more frequently, especially in hot weather.
Spring-Winter · Outdoors
Keep the leaves dry
The leaves should be kept dry, so avoid splashing them while watering.
Winter
Winter · Outdoors
Water sparingly during dormancy
In its dormant period give very little water, keeping the soil barely moist. Dormancy is likely to be during the winter and the plant recommences growth in early to mid spring.
When a plant enters dormancy the leaves fade, go yellow and then brown. Eventually the whole plant may 'disappear' or unadorned stems may remain.
