Bonanza Harmony Marigold is a striking new cultivar that rewrites what compact marigolds can do. Its distinctive double crested flowers bloom reliably in just 50 days, making it one of the fastest marigolds to flower from seed. This open-pollinated variety thrives across hardiness zones 2 through 11, adapting to nearly every North American climate while staying neat and contained at a compact size. Plant it 8 inches apart in beds, borders, containers, or window boxes, and you'll have weeks of color from midsummer straight through frost.

The double crested flower form sets Bonanza Harmony apart from single-flowered marigolds, creating a fuller, more ornamental bloom that catches the eye. At just 50 days to flower, it's remarkably fast, rewarding impatient gardeners with color before summer even peaks. Its compact growth habit and proven container friendliness make it equally at home in a window box as it is anchoring a garden bed, and pinching young plants coaxes even bushier branching for a fuller display.
Bonanza Harmony Marigold is grown as an ornamental flower for garden beds, borders, mass plantings, containers, and window boxes. Its compact habit and rapid flowering make it especially useful for quick seasonal color in small spaces or for gardeners seeking fast gratification from seed.
No timeline data available yet for this variety.
Sow seeds indoors 4 to 6 weeks before your last frost date, lightly covering the seed in a 72-cell flat or standard seedling container. Maintain soil temperatures between 70 and 80 degrees Fahrenheit for reliable germination. For flowering transplants ready to sell or gift, sow 8 weeks before your target bloom date. Bottom heat or a warm seedling mat speeds germination.
Transplant seedlings outdoors only after all danger of frost has passed and soil has warmed; marigolds are frost-tender annuals. Space plants 8 inches apart in beds or containers. Harden off seedlings by gradually exposing them to outdoor conditions over 7 to 10 days before final planting.
Direct sow seeds 1/4 inch deep into warm soil after the last frost date has safely passed. Keep soil evenly moist until seedlings emerge. Thin seedlings to 8 inches apart once they develop true leaves.
Pinch the growing tips of young plants to encourage branching and bushier growth, resulting in more flowers per plant. Deadhead spent blooms regularly throughout the season to redirect energy into new flower production and maintain a compact, tidy appearance.
