How To Grow Snapdragon From Seeds

What are Snapdragons?

Snapdragons, scientifically known as Antirrhinum, are beautiful flowering plants that belong to the Scrophulariaceae family. These plants are native to the Mediterranean region and are popular for their vibrant colors and unique shape. Snapdragons are often used in gardens, borders, and flower arrangements due to their long-lasting blooms.

Why Grow Snapdragons from Seeds?

Growing snapdragons from seeds is an affordable and rewarding way to add these stunning flowers to your garden. By starting from seeds, you have a wider variety of cultivars to choose from compared to buying pre-grown plants. Additionally, growing snapdragons from seeds allows you to witness the entire lifecycle of the plant, from germination to blooming.

Steps to Growing Snapdragons from Seeds

Snapdragon seeds are easy to grow and can be sown outside after final frost, or start indoors 6 – 10 weeks prior to last frost. Freeze seeds for 48 hours before sowing.   

1. Gather the Supplies

Before you begin, gather the necessary supplies:

  • High-quality snapdragon seeds

  • Seed trays or pots

  • Seed starting mix

  • Watering can or spray bottle

  • Plastic wrap or a seed tray cover

  • Grow lights or a sunny location

2. Prepare the Seed Trays

Fill the seed trays or pots with a well-draining seed starting mix. Moisten the mix with water, ensuring it is evenly damp but not soaking wet.

3. Sow the Seeds

Place the snapdragon seeds on top of the seed starting mix, spacing them about 1 inch apart. Lightly press the seeds into the mix, ensuring they make good contact with the soil. Do not cover seeds during germination, just press slightly in the starting mix.

4. Provide Optimal Conditions

Place a plastic wrap or a seed tray cover over the trays to create a greenhouse-like environment. This helps retain moisture and warmth, promoting germination. Keep the trays in a warm location or under grow lights. A full light will help seeds germinate in 8 – 14 days.

5. Water and Monitor

Water the seeds gently using a watering can or spray bottle. Avoid overwatering, as excessive moisture can lead to fungal diseases. Monitor the trays regularly and ensure the soil remains moist but not waterlogged.

6. Transplanting

Once the seedlings have developed their second set of true leaves, they are ready to be transplanted into individual pots or the garden. Harden off the seedlings by gradually exposing them to outdoor conditions before transplanting.

7. Planting in the Garden

Choose a sunny location in your garden with well-draining soil. Dig holes that are slightly larger than the root ball of the seedlings. Place the seedlings in the holes and gently firm the soil around them. Water thoroughly after planting.

8. Care and Maintenance

Water the snapdragons regularly, especially during dry spells. Apply a balanced fertilizer every four to six weeks to promote healthy growth. Remove any weeds or competing plants around the snapdragons to prevent nutrient competition.

9. Enjoy the Snapdragon Blooms

With proper care, your snapdragons will start blooming in early summer and continue to produce flowers until the first frost. Feel free to cut the flowers for beautiful bouquets, as snapdragons make excellent cut flowers.


Growing snapdragons from seeds is a fulfilling and cost-effective way to enhance your garden with these stunning flowers. By following the step-by-step guide outlined above, you can successfully grow snapdragons and enjoy their vibrant blooms throughout the season. So, why wait? Start sowing those snapdragon seeds and witness the beauty unfold!
