Giant Tetra is the commercial name of a snapdragon (Antirrhinum majus) seed mix. These snapdragons bloom in brighter colored flowers with larger florets and thicker petals than common snapdragons. Giant Tetra snapdragons grow to 24 inches in height and bloom right up to the first frost in U.S.
Department of Agriculture plant hardiness zones 7 through 10. Although you can start Giant Tetra seeds right in the garden when the soil warms to 64 degrees Fahrenheit, many gardeners choose to get a head start on the season by germinating them indoors 6 to 10 weeks before the last frost date.
