In many areas, snapdragon seeds will survive low winter temperatures, and new plants will grow from these seeds in spring, making the plant seem as if it came back like a perennial. … Because of their short-lived nature, perennial snapdragons tend to be grown as annuals and are replanted every year.

Can snapdragons reseed themselves?

Do Snapdragons Self-Seed? … Snapdragons propagate either by seed or cuttings. They are considered a “self-seeding” annual. When left alone, seeds from spent flowers will fall to the ground, survive the winter (up to -30 degrees!), and come back the next year as new plants.

How do you get snapdragons to reseed?

Pinch back young flower stalks to encourage bushy, floriferous growth and remove spent flowerheads during the growing season to stimulate regrowth. In early to mid fall, allow spent flowerheads to remain on the stalks, so that the plants will put their energy into producing seeds rather than flowers.
