How many of us, as children, pinched snapdragon blooms between our fingers to see the floral dragon open and close its mouth? Yep, count me in!
Standard snapdragons are classified as midget (6-8”), medium (15-30”), and tall (30-48”). There are also fairy snapdragons (pictured) that provide delicate, miniature versions of the blooms.
How to grow snapdragons
Snapdragons perform best in full or partial sun. They prefer well-drained soil and do well in rockeries. Unlike many other flowers, snapdragons can withstand frost and often provide cool season flowers.
Snapdragons are difficult to start from seed, but it can be done. The normal lifecycle of a snapdragon is to bloom in fall and winter (weather permitting) and then drop seeds in spring. These seeds are exposed to a lot of heat during the summer. If you want to grow snapdragons from seed, simply reproduce that cycle. Cold, damp weather or soil will halt their growth. After flowers have passed their peak, be sure to deadhead the plants for more blooms.
Snapdragon plants can become leggy and may need support. You can reduce this need by pruning the longest stems to form a bushier shape. Regular deadheading will promote more flower development.
Snapdragon pests & diseases
Once established, snapdragons should be allowed to dry out between waterings. They are prone to several fungal diseases, such as:
Anthracnose, root knot nematode, crown gall, and leaf and stem spot are also occasional problems on snapdragon.
