Snap Dragon
Snapdragon
Antirrhinum majus
Aka: Lion's mouth
Size: 6 inches to 3 feet tall
Lighting requirements: Full to part sun
Seasonal interest: Blooms spring through winter in some cases
Winter: Snaps survive very low temperatures, although, they may get damaged by some freezes (wet freezes mainly)
Snaps are a great cool season annual (short-lived perennial if you can get them through the summer). The tall varieties also make excellent cut flowers.
Antirrhinum rust is a fungal disease that can severely affect Snapdragons. It will show up as yellow spots on the upper surface of the leaves and rust colored pustules on the undersides. It can be so serious that the plant and others (Snaps) around it can die. Occasionally, the spores can overwinter and attack again the next year. Treat with neem if you see this beginning. You can also add cornmeal to the soil.
Please don't let the above information scare you away from these beauties! I've grown them every year, and this has only happened once (over 12 years ago!).
