Camphorweed,  Heterotheca subaxillaris 

A tough, drought-tolerant native with bright yellow, long-blooming daisy flowers—perfect for dry, sunny spots! (Also known as Camphor False Golden-aster or Dune Camphorweed)

Requires full, direct sun for robust growth and maximum flower production. Thrives in sandy, gravelly, and otherwise barren soils. Will not tolerate wet or heavy clay. Highly drought-tolerant once established. Water only sparingly; overwatering is the biggest threat. Typically grows as a summer annual, but may overwinter as a leaf rosette (biennial) in warmer regions (Zones 6-9). Grows 2 to 5 feet. Height varies significantly based on conditions; it grows taller in good soil, shorter in very poor soil. A strong self-seeder that spreads readily, best suited for naturalized areas or informal gardens.

Camphorweed seeds exhibit germination dimorphism, meaning two types of seeds in one flower head have different needs. This is a survival strategy, ensuring some seeds germinate quickly (Disc Achenes) and others wait (Ray Achenes). 

Sow in fall (Recommended) directly outdoors in late autumn or use Winter Sowing. The seeds will naturally overwinter, and the non-dormant seeds will germinate the following spring/autumn, with the dormant seeds waiting until the following year. Sprinkle seeds and lightly press them into the soil. Do not cover as they need light to germinate. 

Interesting Facts & Uses

The common name Camphorweed comes from the strong, medicinal, or camphor-like scent released when the fuzzy leaves and stems are bruised or crushed. This scent helps deter grazing animals.

This native plant is a powerhouse in difficult environments, thriving in coastal dunes, disturbed areas, roadsides, and open fields where few other flowers can tolerate the heat, sun, and dry, sandy soil.

Late-Season Nectar: The bright, golden-yellow daisy flowers bloom profusely throughout the summer and continue strongly into the autumn (July through October/November), providing critical late-season pollen and nectar for bees, butterflies, and other beneficial insects.

"Different Containers": The genus name Heterotheca is derived from Greek words meaning "different containers," which refers to the two different types of seeds produced in the same flower head, each with its own size, shape, and unique germination requirements.
