An erect, densely floriferous, well-branched shrub, usually growing to about 1m tall, but it can reach up to 2 m in height. The branches are ascending or nearly erect. Leaves are dark green, linear, simple and whorled. It has masses of small, hairy, white, bell shaped flowers, up to 5 mm long. The flowers are entirely covered in white woolly hairs and when in full flower, it appears that the bushes are covered in snow! A simply stunning sight. It flowers from late winter into spring.
