How to Grow Snapdragons


Snapdragons (scientific name Antirrhinum majus) are colorful and fun additions to any flower garden. They are easy to grow, and children love to squeeze the flowers, sometimes called "dragon's snout," and watch the "jaws" open. Snapdragons are considered annuals in zones 2 through 8, but will often go to seed and may surprise you the following year by coming back. In zones 9 through 11, they're considered perennials.

Step 1

Choose a site that has full sun (afternoon shade in warmer climates) and well-drained, fertile soil. Plants can be planted in the spring after the last frost or, in Southern areas of the United States, in the fall.

Step 2

Dig a hole with the trowel and place it in the hole. Fill in the soil, compacting as you go to remove any air pockets. Water generously. If planting more than one, space them 6 to 8 inches apart.

Step 3

After young plants are about 3 or 4 inches high, pinch back the stems with your fingers to encourage a bushier plant that will yield more flowers.

Step 4

Remove any spent flowers throughout the growing season by pinching them off with your fingers. This will keep the plant flowering well into the fall.

Step 5

To keep your snapdragons for the following year, leave the flowers intact after the last bloom. These will go to seed. New seedlings in the spring can then be transplanted elsewhere.
