Thymophylla tenuiloba
Bristleleaf Pricklyleaf (Dahlberg Daisy) is a bushy, aromatic native annual or short-lived perennial characterized by threadlike, needle-fine foliage that emits a crisp, pungent citrus aroma when crushed. Spreading into glowing golden carpets across sunny limestone outcrops, gravelly slopes, and roadsides, it flowers continuously from spring until first freeze. Its pungent essential oils render it completely immune to deer browsing, while its dense flower heads supply steady nectar for solitary bees, sulfur butterflies, and beneficial predatory wasps that regulate garden pests.
