Antirrhinum majus, known on its common name as Snapdragon, is an easy to grow annual that makes an excellent choice for planting in beds, borders, edgings and containers but you can try to plant them in rock gardens or window gardens too, depending on their height category: tall, medium or dwarf. This flower is a real joy for children, who love to pinch the flowers and make the "dragon mouth" open and close.
Snapdragons are very hardy plants that can withstand a heavy frost and can endure cool weather. That is why they are widely planted for winter flower colors in mild-winter areas. In colder areas they will flower from spring to early summer but most varieties will also have a second bloom in fall. The gradual opening of the buds provides color for an extended period of time. Snapdragon flowers are very colorful, from white to yellow, red, pink, orange and bronze and also different hues of those colors.
Snapdragons grow best in a place with full sun or light shade, in rich, well-drained soil, with plenty of organic matter. They will thrive in average soil, but is best to add a general purpose fertilizer before planting, if the soil is poor.
Propagation of Snapdragons is made by its tiny seeds. The seeds need about three weeks or more to germinate. Sow seeds indoors about 6-8 weeks before the last frost in your area. Plant Snapdragons outdoors after the last frosts have passed. Fertilize once a month if the soil is poor. Pinch the tips of young plants to encourage branching. Tall varieties need to be staked to prevent breakage. Stake the plants early in the season. For cool season bloom, plant Snapdragons in early autumn. After the flowers have died off, cut the plant back to about 15 cm, then add fertilizer. This will promote new growth and a second bloom later in the season. If you want you can let those plants to grow freely in your garden as they are self-sowing. Leave one or two flower stalks to ripen and self-sow seedlings for the next year.
