Rocket Snapdragons are a hybrid snapdragon bred for cut flower growers reaching heights of 36" with large azalea type petals. Rocket snapdragons are also bred for heat resistance and will last the longest as compared to the other hybrid snapdragons such as Potomac, Chantilly, Madame Butterfly, and others.
You can direct seed these but they are very slow growing in the garden and tend to get overwhelmed by other weeds and flowers. For zones 7-9 it's also best to follow the directions below and start them early so they get established before your summer heat arrives.
For zones 3-10 we find they are best seeded in trays about 10 weeks before your last frost in the spring. Seedlings will take a light freeze and here in zone 7 we generally put them out in our garden in late February or early March as they like cold weather to set their roots. They prefer very rich soil and flourish with moist soil conditions. The seeds require light for germination so when we start them in trays we sow them on the surface of our potting material and then cover them very lightly with fine sand or fine vermiculite. They are quick to germinate but slow to grow. In zone 7 they do not have a lot of growth until May and then flower from June to July. Once in the garden, and about 6" tall, you can pinch the center stalk to force the plant to create more blooms. These side blooms won't be as tall as the center stalk but you will generate more flowers.
