Effects
Description
- Their botanical name, Antirrhinum, means \"like a snout\" and refers to the seed pod's resemblance to a calf's nose. The flowers resemble opening mouths when they are pressed on their sides. The openings of the flowers are snapped tightly shut and require more pressure to open than a honeybee can provide, so snapdragons rely on heavier bumblebees for their pollinat…
Cultivation
- Snapdragons are undemanding and can grow in a wide selection of colors and heights. They are at their best in cool weather. Snapdragons are tender perennials that are only hardy in U.S. Department of Agriculture Hardiness Zones 8 or 9. They can repeat bloom throughout the season but do best in the cool of spring and fall and throughout the winter in mild climates. Deadheadin…
Culture
- Snapdragons prefer cooler temperatures. Snapdragons grow best when nighttime temperatures are in the low 40s and daytime temperatures in the low 70s Fahrenheit. Once established in the bed and hardened off, they can withstand sub-freezing temperatures. Make sure they stay well watered during cold spells and add a layer of pine straw mulch, and they can last for quite some …
Prevention
- Apply fertilizer when the plants first start producing flowers. Use a standard, well-balanced all-purpose fertilizer, such as a 10-10-10 product, at a rate of three pounds for every 100 square feet of the flowerbed. Water well to minimize the risk of nitrogen burns and to help the fertilizer reach the roots.

- Their spiky, bright colored flower stalks make a nice foil for the cooler shades of most spring flowers like brunnera and bleeding heart. Planted in clusters, they can help a border transition from the spring ephemerals to peak hot season.
Characteristics
- The pale yellow varieties are the easiest to blend into a mixed border and work nicely with pinks, purples, and even reds.
