Should I pull my short plants this fall or if I leave them in the ground for the winter, might they grow in the spring?
Snapdragons as Perennials
Certified GKH Gardening Expert
You can pull them, leave them, or harvest seeds. Most snapdragons are self-seeding annuals, so they will come back each year, but they are not necessarily going to be the same plants as the year before. There are a few varieties that are considered perennial, in Zones 9-10; however, most are not. Many of the seeds remain cold hardy to -30 so they will normally remain viable throughout winter and new plants will pop up in the spring.
