Diosma echinulata features small, needle-like leaves and a compact, rounded growth habit. Its tiny white to pinkish flowers, each edged with fine, bristly hairs, appear in clusters, giving it a distinctive, frothy appearance. Adapted to its native fynbos habitat, diosma echinulata thrives in well-drained soils and is resilient to the dry, windy conditions prevalent in these ecosystems. The shrub's dense foliage is both a refuge for insects and a fragrant addition to the landscape.
