The Unique Flower With Hinged Blooms: Snapdragons (Antirrhinum majus) are vibrant, unique flowers known for their hinged, dragon-like blooms that “snap” when pinched, hence their name. These flowers come in a range of colors, making them a popular choice for gardeners looking to add striking color and charm to their landscapes.
Growing snapdragons is relatively easy with the right conditions, and they can thrive in various climates. This guide will provide you with everything you need to know about growing and caring for snapdragons.

Step-by-Step Guide to Growing Snapdragons
1. Choose the Right Location
Snapdragons grow best in full sun but can tolerate partial shade, especially in hotter climates. Ensure the planting site gets at least 6 hours of sunlight daily. For the best bloom production, choose a location that provides plenty of morning sun with some afternoon shade in hotter regions.
2. Prepare the Soil
Snapdragons prefer well-draining soil rich in organic matter. Loamy or sandy soil with a slightly acidic to neutral pH (6.0-7.5) is ideal. Before planting, work compost or well-rotted manure into the soil to improve fertility and drainage. Make sure the planting bed is free of weeds, as snapdragons don’t compete well with aggressive weeds.
3. Planting Snapdragons
Starting from Seeds: Snapdragons can be started from seeds indoors 6-8 weeks before the last frost. Sow the seeds on the surface of moist seed-starting mix, as they require light to germinate.
Keep the soil temperature between 65-70°F for optimal germination. Transplant the seedlings outdoors when they are about 3-4 inches tall, spacing them 6-12 inches apart depending on the variety.
Transplanting Seedlings: You can also buy young snapdragon plants from nurseries and transplant them directly into your garden. Ensure that you plant them at the same depth they were growing in their pots.
4. Watering and Mulching
After planting, water thoroughly to help the plants establish. Snapdragons prefer moderately moist soil, so water them regularly, especially during dry spells.
However, avoid overwatering, as they are prone to root rot in soggy soil. To conserve moisture and suppress weeds, apply a 2-inch layer of organic mulch around the plants, such as straw or shredded leaves.
5. Fertilizing
Snapdragons are not heavy feeders, but applying a balanced fertilizer (like 10-10-10) at planting time can promote healthy growth and abundant blooms. You can also use a liquid fertilizer every 4-6 weeks during the growing season. Avoid over-fertilizing, as this can lead to lush foliage but fewer flowers.
6. Deadheading for More Blooms
To encourage continuous blooming throughout the season, deadhead (remove spent flowers) regularly. Snapdragons are prolific bloomers, and deadheading helps redirect the plant’s energy into producing new flowers instead of seed pods. Simply pinch off the faded blooms or use pruning shears to cut them back.
7. Supporting Tall Varieties
Some taller snapdragon varieties can grow up to 3 feet and may need staking to prevent them from toppling over, especially in windy areas. Insert stakes early in the growing season and tie the plants loosely to provide support as they grow.
8. Pests and Diseases
Snapdragons are generally resilient, but they can be affected by common garden pests like aphids, spider mites, and caterpillars. Treat infestations with insecticidal soap or neem oil. Additionally, watch out for fungal diseases like rust or powdery mildew, which can occur in humid conditions.
To prevent disease, water the plants at the base and avoid wetting the foliage. Good air circulation between plants also helps prevent fungal issues.
Snapdragons in Winter
In USDA zones 7-10, snapdragons are often grown as short-lived perennials and can survive mild winters. However, in colder climates, they are usually treated as annuals.
If you want to extend their growing season, mulch the base of the plants with straw or leaves before the first frost. Alternatively, you can dig up the plants and move them to containers indoors.
Unique Tips for Thriving Snapdragons
Pinch the Tips for Bushier Plants: Once your snapdragon seedlings are about 4 inches tall, pinch off the growing tips. This encourages the plant to grow more side branches, resulting in a bushier, fuller appearance with more blooms.
Cutting for Bouquets: Snapdragons make excellent cut flowers and can last up to 10 days in a vase. Cut them early in the morning when the lower flowers on the spike have opened. Trim the stems at a diagonal and place them in water immediately.
Succession Planting: For continuous blooms, practice succession planting. Plant new snapdragons every few weeks throughout the growing season, especially in cooler regions where the plant may not last as long in hot summer weather.
Nutrition and Benefits of Snapdragons in Gardens
Snapdragons are not only beautiful but also attract beneficial pollinators like bees, butterflies, and hummingbirds, which helps in maintaining a healthy garden ecosystem. They also act as companion plants, warding off certain pests such as aphids and nematodes that can damage nearby crops.
Conclusion
Growing snapdragons is a rewarding experience, as their colorful, unique blooms can brighten any garden. By following these care tips and giving them the right conditions, you’ll enjoy a vibrant display of hinged flowers from spring until fall. Whether grown as annuals or perennials, snapdragons add charm, color, and life to any landscape.
