Description:

Sulphur Cosmos are a clump-forming annual wildflower native to Mexico, known for its vibrant flowers in shades of gold, orange, red, and yellow. Growing between 2 to 4 feet tall, it thrives in a variety of habitats, including home gardens, beds and borders, pollinator gardens, and wildflower meadows. This adaptable plant can tolerate poor soils and hot, arid climates, flourishing in temperatures exceeding 100°F. It prefers light, well-drained soil and full to partial sunlight, blooming from late spring to autumn. Sulphur Cosmos are also abundant self-seeders that attract honey bees, wild bees, butterflies, and birds, making them an excellent choice for biodiversity in gardens.

 

The uses of Sulphur Cosmos extend beyond their aesthetic appeal. They make ideal cut flowers and are effective for pollinator gardens, contributing to the health of local ecosystems. Their resilience means they can thrive even in neglected areas, requiring minimal maintenance. Additionally, planting them in more infertile soil can enhance their growth, as fertilization may lead to overgrowth and instability. In colder, more moist climates, it’s best to plant seeds in spring, while in drier regions.
