Snapdragon

Antirrhinum majus

Growth Potential

Height: 1-3 feet | Width: 0.5-1 foot

Cool-season color from fall through spring

Snapdragons are one of the best cool-season annuals for North Texas. Planted in fall, they bloom through mild winters and spring in a wide range of colors, then fade when summer heat arrives.

They add upright color to beds and pots when most summer flowers are done, and they make a lovely cut flower.

Best Area to Plant

Location:

  • Front and middle of sunny beds
  • Containers and window boxes
  • Cutting gardens
  • Entry beds for winter and spring color

Placement:

Plant in fall in full sun, about 8 to 12 inches apart, in well-drained soil. Improve heavy clay with compost. Keep them away from spots that stay soggy in winter and plan to replace them with heat-tolerant flowers in late spring.

Care Instructions

  • Light:

    Full sun, at least 6 hours a day.

  • Water:

    Water regularly, about once or twice a week depending on rainfall. Keep the soil evenly moist but not soggy.

  • Maintenance:

    Pinch young plants for bushier growth and deadhead spent spikes to keep blooms coming. Protect with a cover during hard freezes. It is a cool-season annual and fades in summer heat.
