Safety Overview
1.Cosmos Atrosanguineus — Essential Profile
Cosmos Atrosanguineus, commonly known as Chocolate Cosmos, is a captivating perennial herb belonging to the Asteraceae family. This distinctive plant is characterized by its upright, slender stems, typically reaching heights of 40 to 60 centimeters. Its foliage consists of lanceolate to pinnatifid leaves, measuring approximately 5-15 cm in length, often exhibiting a deep green hue.
The most striking feature of Cosmos Atrosanguineus is its unique, velvety, dark reddish-brown to maroon flowers, which emit a delightful fragrance reminiscent of vanilla or dark chocolate, especially pronounced in warm afternoon sun. These solitary or loosely clustered blooms, about 3-5 cm in diameter, appear from mid-summer through autumn, attracting a variety of pollinators, including bees and butterflies, contributing significantly to garden biodiversity.
Native to Mexico, specifically the high pine-oak forests, Chocolate Cosmos thrives in well-drained, fertile soils with a preference for full sun exposure, though it can tolerate light partial shade. It is often found naturally in open woodlands and grasslands. As a tender perennial, it is typically grown as an annual in colder climates or overwintered indoors, as its tubers are not frost-hardy.
The plant forms a tuberous root system, which allows it to persist year after year in suitable environments. Its ornamental appeal, coupled with its distinctive aroma, makes it a cherished addition to borders, containers, and cut flower arrangements, offering both visual and olfactory delight.

11.Cosmos Atrosanguineus — Cultivation & Care
- ✓Soil Preparation — Cosmos Atrosanguineus thrives in well-drained, fertile soil enriched with organic matter; a slightly acidic to neutral pH (6.0-7.0) is ideal.
- ✓Sunlight Requirements — Provide full sun exposure for at least 6-8 hours daily to ensure vigorous growth and abundant flowering, though it tolerates light afternoon shade.
- ✓Watering Regimen — Maintain consistent soil moisture, especially during dry spells, but avoid waterlogging; water deeply when the top inch of soil feels dry.
- ✓Fertilization — Feed with a balanced liquid fertilizer every 2-4 weeks during the active growing season (spring to autumn) to promote flowering.
- ✓Propagation — Propagate primarily from tubers in spring or from seeds, though seed viability can be low for cultivated varieties; stem cuttings can also be rooted.
- ✓Pest and Disease Management — Generally robust, but monitor for aphids, slugs, and snails; ensure good air circulation to prevent fungal diseases like powdery mildew.
