Introduction Chantilly Bronze Snapdragon (Antirrhinum majus) is a standout snapdragon variety admired for its soft, cascading flower spikes and warm bronze-peach color. It is a favorite among U.S. gardeners and cut-flower growers because it performs well in cooler seasons and adds elegance to both gardens and floral arrangements. With proper care, Chantilly Bronze Snapdragon grows easily from seed and produces abundant blooms.
1. How to Grow Chantilly Bronze Snapdragon Seeds Start Chantilly Bronze Snapdragon seeds indoors 8–10 weeks before your last frost date. Use a fine, well-draining seed-starting mix. Do not cover the seeds, as snapdragon seeds need light to germinate. Press seeds gently onto the soil surface and mist lightly to keep them moist. Maintain temperatures between 60–70°F for best germination. Seeds typically germinate in 7–14 days. Provide bright light immediately after seedlings emerge to prevent stretching. Transplant seedlings once they have 2–3 true leaves. Harden off plants before moving them outdoors. Plant in full sun to light shade, spacing plants 6–9 inches apart.
2. How to Care for Chantilly Bronze Snapdragon Plants Water regularly, keeping the soil evenly moist but not waterlogged. Grow plants in well-drained, moderately fertile soil. Feed with a balanced fertilizer every 2–3 weeks during the growing season. Chantilly Bronze Snapdragon performs best in cool to mild temperatures, producing the most flowers in spring and fall. In hot weather, light afternoon shade helps extend the blooming period. Deadhead spent blooms or cut stems regularly to encourage continuous flowering. Provide support if plants become tall, especially in windy locations. Monitor for common garden pests such as aphids and spider mites, and ensure good air circulation to reduce disease pressure.
