Heterotheca shevockii Flower flinton lg

Heterotheca is a genus of flowering plants in the family Asteraceae. Commonly known as camphorweed or golden aster, these plants are native to North America, particularly the United States and Mexico. The genus is characterized by its yellow flowers and aromatic foliage.

Description

Heterotheca species are herbaceous perennials or annuals. They typically have hairy stems and leaves, which can be glandular and aromatic. The leaves are usually alternate and can vary in shape from linear to lanceolate. The flowers are arranged in heads (capitula) that are composed of both ray florets and disc florets. The ray florets are typically yellow, while the disc florets can be yellow or brownish.

Habitat

Heterotheca species are commonly found in a variety of habitats, including prairies, open woodlands, and roadsides. They are well-adapted to dry, sandy, or rocky soils and are often found in disturbed areas.

Species

There are several species within the genus Heterotheca, including:

• Heterotheca subaxillaris - Camphorweed
• Heterotheca villosa - Hairy golden aster
• Heterotheca sessiliflora - Sessile-flowered golden aster

Uses

Some species of Heterotheca have been used in traditional medicine for their purported anti-inflammatory and antimicrobial properties. However, scientific studies on their efficacy are limited.

Conservation

While many species of Heterotheca are common and not considered at risk, habitat destruction and changes in land use can impact local populations. Conservation efforts focus on preserving natural habitats and promoting the growth of native plant species.
