Plant Common Name

Narrow-leaved Treasure Flower

General Description

Forming a mat of slender, dark green leaves, narrow-leaved treasure flower produces many the golden orange flowers in spring and summer. It is an alpine species that exists at higher elevations in southern Africa, so it’s quite cold hardy if provided moderately dry growing conditions in winter. In frost free areas it is evergreen but may become semi-evergreen or die back to the ground where winters are dip below freezing.

The plant forms spreading rosettes of narrow, long-stemmed leaves of dark green or deep gray-green. In the warmth of spring and summer, golden orange daisies with a brown rings around their centers dot the foliage. The flowers close at night and on overcast days. Bees frequent the blooms and fuzzy seedheads follow.

Grow narrow-leaved treasure flower in full to partial sun and well-drained, average to nutrient poor soil with a neutral to alkaline pH. Sand or gravelly loams are best. This alpine groundcover is drought tolerant and great for rockeries, dry hillsides or containers. The common cultivar, 'Colorado Gold', is extra vigorous and heavy flowering.
