Sulphur Cosmos

Cosmos sulphureus

The perfect scatter seed flower in rich deep golden hues.

These cosmos are wonderfully easy, drought-tolerant, and disease-resistant. A lacy-leaved and flat-bloomed answer to calendula (in the same terrific golden hues). The foliage is robust by late summer, forming a beautiful rounded clump of thin-leaved green that suggests dryland plants. Pairs well with Spider Flower (see photo).
