Add Some Snap to Your Garden with Snapdragons!

 

Snapdragon’s Latin name is Antirrhinum majus. Snapdragons are native to the southern Mediterranean and are members of the Figwort family.[458]

Snapdragons are easy-to-grow, hardy annual flowers that grow well for most people.  Snapdragons get their name from their flowers that “talk” when the flower’s corolla tube is squeezed.  Kids cannot resist snapping snapdragon flowers.[458]

How to Grow Snapdragon Flowers

 

Snapdragon plants are hardy annuals or short-lived perennials that survive average winters in USDA climate zones 8 to 10. Plant in the fall or winter in southern gardens.  Plant snapdragon plants in spring in USDA climate zones 3 to 7. Snapdragons are cold hardy to 15 degrees. Sometimes, snapdragons will come back for a second year in mild-winter, cool-summer climates.[458]

Snapdragons need full sun (six to eight hours) and moist, well-drained soil.  Plants tolerate acid or alkaline soils. They do not flower well in the shade.[458]

Snapdragons bloom best during cool weather when the temperatures range between 40 F and 80 F.  Keep snapdragon plants well-hydrated and as cool as possible to extend the blooming season as long as possible into the summer.[461]

Fertilize snapdragon plants with a time released fertilizer (like Osmocote) or use a water-soluble fertilizer (like Miracle Grow). Plants grown in well-amended garden soil need less fertilizer.  Too much fertilizer makes tall varieties floppy.  [461]

 

 

Can Snapdragons Grow in Pots or Containers?

 

Snapdragons grow well in containers or pots.  Plant them in the center of a mixed container planting to add height and drama.  Water frequently to keep the soil moist; snapdragons do best when they are not subjected to extremes in soil moisture.[458]

 

 

Snapdragons in the Landscape

Plant snapdragons in flower beds and border for spring and summer color.  Mass plantings are stunning and ensure great curb appeal when planted in the front yard.  Tall varieties of snapdragon are good for cut flowers.[458][461]

Snapdragon Height and Plan Form

 

Snapdragons are free-flowering and make good bedding plants.  [458]

Snapdragon plants are upright in form. Flowers are formed on the upper part of the flower spike.  After the main flower spike flowers, shorter side branches continue to grow more blossoms. Cut off old flowers to encourage new blooms. Flower color ranges from reds, pinks, yellows, white and maroon and lavender, but not true blue or purple.[458]
Space dwarf and intermediate varieties 6 to 8 inches apart.  Plant larger varieties 12 inches apart.[462]

 

Grow Snapdragons from Seed

Snapdragons are easy to grow from seed. Sow seeds indoors in high-quality seed starting mix.  It can take up to 3 weeks for the seeds to germinate. [461] Snapdragon seeds need light to germinate. Sprinkle seeds on the soil surface and lightly press into the seed starting media to ensure good contact with the soil.  Start six to eight weeks before you plan to transplant the seedlings into the garden. Use fresh seed because germination rates fall rapidly with age.[462]

Pests and Diseases

 

Although snapdragons are easy-to-grow annual flowers, there are a few pests and diseases that affect the plants.  Rust, a fungal disease, attacks snapdragon foliage.  Rust causes yellow spots on top of the leaves and orange dots on the underside.  Treat rust with commercial fungicides or organically with Neem oil.  Aphids can sometimes be a problem.  Wash aphids off with a jet of water or use insecticidal soap.
