Ease of Cultivation and uses: Cosmos ‘Bright Lights’ is a striking annual flower known for its vibrant, colorful blooms that bring a cheerful atmosphere to any garden. This variety is relatively easy to grow, making it a perfect choice for both novice and experienced gardeners. ‘Bright Lights’ thrives in warm conditions and can be used in borders, wildflower gardens, or as cut flowers to brighten indoor spaces, attracting pollinators like bees and butterflies.

Direct Sowing: For direct sowing, plant ‘Bright Lights’ seeds outdoors after the last frost date when soil temperatures are consistently between 70°F and 85°F. Sow the seeds 1/4 inch deep, spacing them 12–18 inches apart in well-drained soil. Germination typically occurs within 7–14 days, so it’s important to keep the soil evenly moist during this time. Cosmos prefer full sun and can tolerate poor soil, making them a versatile option for various garden settings.

Early Sowing for Seedlings: For an earlier start, sow seeds indoors 4–6 weeks before the last expected frost. Use seed trays filled with quality seed-starting mix, planting the seeds 1/4 inch deep. Maintain a temperature of 65°F to 70°F to promote germination. Once seedlings develop true leaves and the danger of frost has passed, transplant them outdoors, spacing them 12–18 inches apart. Water well after transplanting to help them establish in their new environment.

Harvesting: To determine when to harvest ‘Bright Lights’ Cosmos, look for blooms that are fully open and vibrant in color. The best time to cut flowers is in the morning after the dew has dried. Use sharp scissors or pruners to snip the stems at an angle for better water absorption. These flowers can be used fresh in arrangements or dried for long-lasting enjoyment. For drying, hang the flowers upside down in a cool, dark place until they are completely dried, preserving their bright colors and delicate beauty.
