How To Grow Snapdragons (Antirrhinum Majus)

Snapdragons, or Antirrhinum majus, are flowers that can handle cold temperatures, but not heavy freezes.
Antirrhinums are more commonly known as Snapdragons, they are a fragrant genus of flowering plant, containing around 36 species, belonging to the Plantaginaceae family. These plants resemble the face of a dragon that opens and closes its mouth when squeezed, hence the ‘snap’.
Snapdragons need full sun, and grow well in most types of neutral soil with a pH between 6.2 and 7.

Snapdragons come in a wide range of colours including purple, yellow, white, crimson, pink and bronze. They are native to the Mediterranean though they will grow well in English flower beds and rock gardens.



Gardening Tips

  1. These flowers should be planted outside after the last frost in your area.
  2. These plants like to be in full sunlight and need to be situated in average soil that offers good drainage.
  3. Snapdragon seedlings can be bought from your local garden centre, and need to be planted 1 – 2 inches deep with about 15 – 30 centimetres between each seedling, as larger species can grow between 30 and 48 inches high.
  4. Watered in the seedlings but do not over water.
  5. The plants should be watered in the morning, as leaving the plants wet at night can lead to distorted growth and rotting of the roots.
  6. Snapdragons will bloom around June and the tallest growing shoots should be pinched out when they are around 3 inches tall to encourage branching and more flowers.
  7. Once the flowers have died off, cut the plant back to around 6 inches, which will then promote new growth and a second bloom if well fertilised.
  8. If you are growing the taller varieties of snapdragon, be sure to stake them to provide them with extra strength.

Snapdragons are very hardy annual flowers that can withstand a heavy frost and will provide beautiful colour in your garden for the entire summer. Snapdragons are usually treated as annuals in temperate climates.
