About this plant
This delicate, pretty plant has slender, grey-green hairy leaves that make a somewhat indeterminate mat. The warm, canary-yellow flowers are delightful, held above the foliage on strong stalks. These each bear several pendulous, tubular flowers that open out slightly towards their mouths and are partially encased by a pale-green, corset-like calyx.

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.
