Description




Selected high-vitality cosmos seeds ensure stable high germination rate. Cosmos bipinnatus is one of the most effortless annual ornamental flowers, featuring lacy feathery foliage and airy branching stems topped with elegant daisy-shaped blossoms.
It performs outstandingly under high temperature and dry conditions, keeping blooming nonstop from early summer until the first frost. Widely used in cottage gardens, wildflower meadows, roadside mass greening, flower bed borders and fresh cut flower bouquets. Open flowers attract plenty of bees and butterflies to build a vivid pollinator garden ecosystem.
Cosmos prefers lean, well-drained soil; overly fertile soil causes leggy lodging and fewer flowers. Only basic drought watering and regular deadheading are needed, extremely suitable for beginners and large-scale ecological landscaping.

Step-by-Step Planting Instructions for Cosmos Seeds
