Chocamocha Cosmos is a stunning heirloom variety that brings rich, deep burgundy flowers to your garden from summer through fall. These chocolate-toned blooms grow on compact plants reaching just 18 to 24 inches tall, making them excellent for borders, containers, and mixed plantings in USDA zones 9 and warmer. Despite their delicate appearance, these cosmos are surprisingly tough, thriving in full sun with minimal water once established and attracting pollinators throughout the season.

The flowers themselves are the star here, displaying that distinctive dark, almost chocolate-brown color that gives the variety its name. These cosmos bloom generously from June through November, providing months of color when many other flowers are fading. They're naturally drought tolerant and deer resistant, making them reliable performers in challenging garden spots, while their compact 18 to 24 inch height keeps them tidy without constant pruning.
Chocamocha Cosmos are grown primarily as ornamental flowers for garden displays. Their long bloom season and deep coloring make them excellent choices for cutting arrangements, border plantings, and container gardens where you want sustained color from early summer into late fall.
No timeline data available yet for this variety.
Start seeds indoors 4 to 6 weeks before your last frost date in a warm location maintained at 65 to 75°F. Sow seeds at a shallow depth and keep the soil consistently moist but not waterlogged until germination occurs.
Transplant seedlings outdoors after the last frost date has passed, hardening them off gradually over 7 to 10 days by exposing them to outdoor conditions for increasing periods. Space plants about 1 inch apart in their final location.
Direct sow seeds in the garden after all danger of frost has passed, planting at a shallow depth in prepared soil.
