Snapdragon (Antirrhinum Majus Maximum Ruby) - This annual is a favorite flower in gardens of North America because it readily establishes from Snapdragon seeds, and it gives an incredible display of colorful blooms. This tall red Snapdragon is incredibly beautiful! Millions of Snapdragon flowers are grown in greenhouses to be used as cut flowers for florists. They are an all-around excellent performing flower. Most cultivated Snapdragons belong to the species Antirrhinum majus, a native of the Mediterranean region. There are more than 30 species of Snapdragon plants in Europe and North America. The showy, two-lipped flowers are about 1 1/2 inches long. The lower blossoms open first and then on up to the top of a tall stem.
Dark Red Snapdragons should be grown in rich, well-drained soil. Grow them in full sun, and space this tall variety 12 - 18 inches apart. After they are done blooming, trim the plants back, and they will quickly be blooming again. Snapdragons perform best in cooler summer climates. In hot regions, provide Snapdragon plants with some afternoon shade.
How To Grow Snapdragons From Seeds: Snapdragon plants can tolerate a light frost, so they can be set out as early as the ground can be worked. For the earliest blooms, sow Ruby Red Snapdragon seeds indoors 6 - 8 weeks before setting the plants out. Use quality starter mix and sow the Snapdragon seeds on the surface of the pre-moistened mix and gently press the seed in. Harden off the Snapdragon seedlings for 10 - 14 days before planting outdoors. Pinch back at the time of transplanting to encourage branching. For areas with mild winters, sow Snapdragon flower seeds outdoors in a sheltered seed bed in late summer. Transplant the young Snapdragon plants into their permanent location for blooms in winter and spring.
