Scabweed. Has grey-blue leaves so small the plant appears like a velvety mould creeping over gritty soil, soft to touch,( ie not a hard mat), powdered with minute yellow flowers in spring. Ideal trough plant. Protect from excessive winter wet as portions can die back. One way is to provide a layer of 5mm chip or sand. Ensure free draining soil. Easy and hardy, drought tolerant once established. Native. 2cm
