- Species and varieties: Snapdragons (Antirrhinum majus) are a popular garden flower known for their vibrant colors and unique flower shape. The white snapdragon is a variety of this species, characterized by its pure white blooms.
- Hybrid or heirloom: White snapdragon seeds can be found in both hybrid and heirloom varieties. Heirloom varieties are open-pollinated and have been passed down through generations, while hybrid varieties are bred for specific traits such as disease resistance and uniformity.
- Pruning and training: Regular deadheading (removal of spent flowers) encourages continuous blooming. Pinching back the stems when the plants are young can promote bushier growth. Staking may be necessary for taller varieties to prevent them from toppling over.
- Fertilization needs: Snapdragons benefit from a balanced, all-purpose fertilizer applied at planting time and then every 4-6 weeks during the growing season. Avoid over-fertilizing, as this can lead to excessive foliage growth at the expense of flowers.
- Hardiness zones: Snapdragons are suitable for USDA hardiness zones 7-10. They can be grown as annuals in cooler climates and as perennials in warmer regions.
- Climate requirements: Snapdragons prefer cool weather and can tolerate light frost. They thrive in temperatures between 60-75°F (15-24°C). In hotter climates, they may require some shade during the hottest part of the day.
