Growing snapdragons like a pro is not as difficult as you might imagine. These classic annual plants produce dozens of 1-inch blooms on stalks that range from 8 inches to 3 feet. Blooms begin in the early summer and range in color from pastels to deep shades of color.

Select one or two snapdragon plants for seed harvest and allow the blooms to mature and fade. Cover a flower spike with a paper bag and seal the bag to the spike with string or an elastic band. Allow the seeds to ripen and then cut the flower spike from the plant. Shake the spike in the bag to dislodge seeds. Collect seeds and store them in a cool, dry place.
