Snapdragons are [[perennial plants]] often sold as cold-season [[annual plants]] and do best in full or partial sun. They are available in a range of heights: ''dwarf'' (6-8 inches), ''medium'' (15-30 inches) and ''tall'' (30-48 inches). Plant them in a soil that drains well to prevent the roots from rotting. | Snapdragons are [[perennial plants]] often sold as cold-season [[annual plants]] and do best in full or partial sun.
