May in the Yangtze River south of the overwintering, the North need to protected winter, is winter and spring flower beds, reading glasses, an excellent choice.
Different varieties of Antirrhinum majus large difference in plant height, from the 20-70 cm range can meet a variety of flower beds on the plant height different requirements.

Based on personal preferences and flower beds need to select varieties of Antirrhinum majus. If the winter temperature for the growth of Antirrhinum majus, and there are no special requirements on the plant height, choose dwarf plant type Antirrhinum majus. Because dwarf plant type goldfish flower a long period, can reduce the workload for flowers. Such as in cold areas, goldfish, grass planted outdoors in the spring only, it should be under the flower bed on the plant height requirement to select varieties. There are dwarf plant type Antirrhinum majus ‘thumb Fairchild’, ‘Concerto’, ‘Huayu’, ‘Bells’, etc. In addition to these varieties are different colors, all the other characters was no significant difference.

High temperatures during the seedling planting, pay attention to ventilation, cooling, timely shade. As the snapdragon seeds is very small, breeding more difficult, according to the author experience, in ordinary steel canopy planting (with film coverage), the import rate of seed into a seedling about 30%, domestic seeds in about 5%, while not high, but Basic no longer die after emergence. Snapdragon grow faster, we must promptly fertilization, when plants have 2-3 pairs of true leaf, when transplanted, grow to four pairs of leaves to remain the top three pairs of leaves to play, so that you can get a six flower heads into the flowers.
