Summary

Cosmos sulphureus, commonly known as Sulphur Cosmos, is an annual herb that thrives in open woodlands, grasslands, and disturbed areas in Central America and Mexico. It can grow to a height of 1–7 feet (30–210 cm) and has a bushy habit with fine-textured, opposite, pinnately divided foliage. The flowers, which bloom from mid-summer to frost, are daisy-like with a range of warm colors including yellow, orange, and red, and are highly attractive to pollinators such as bees and butterflies.

Sulphur Cosmos is valued for its vibrant, long-lasting blooms and its ability to adapt to poor, dry soils, making it an excellent choice for adding color to low-maintenance gardens. It is often used in mass plantings for a bold display of color and is popular in urban landscapes, cottage gardens, and as a border plant. It is also used in cut flower gardens due to the longevity of its blooms in arrangements. Sulphur Cosmos prefers full sun but can tolerate partial shade, and while it is drought-tolerant after germination, it benefits from regular watering during prolonged dry periods. It is not typically bothered by pests or diseases, making it a trouble-free addition to the garden. However, it can self-seed prolifically and become invasive in some regions, so gardeners should manage its spread responsibly.CC BY-SA 4.0
