How to Grow Snapdragon Plant Profile

A cheerful flower that children love to play with, snapdragons have been popular in cottage gardens for years.

Cultivation Information and How to Grow Snapdragons

Botanical and Common Name – Antirrhinum majus is the scientific name for the Snapdragon plant.

Plant Category – Snapdragons are self-sowing annual plants.

Bloom Time and Color – They are cool-season annuals that bloom all spring through early summer in nearly every available flower color, or bicolor, except blue and green. With cutting back in the summer many snapdragons will rebloom when cooler fall temperatures arrive.

Foliage – The foliage is attractive with narrow, dark-green leaves.

Growth Habit – Snapdragons have a narrow, upright growth habit that adds a gentle vertical contrast to the garden.

Dimensions – While most snapdragon plants grow about 3′ tall, dwarf varieties are also available.

Preferred Conditions – Snapdragons prefer full sun, regular water and rich, well-drained soil.

Maintenance – The only true maintenance needed with snapdragons would be cutting the plants back and watering deeply in the summer heat after flowers fade. Often this will cause another flush of blooms in the fall. Many gardeners, however, prefer to leave one or two flower stalks to ripen and self-sow seedlings for the next year.

Pests or Diseases – Snapdragon rust can be a problem but disease resistant varieties and adequate air circulation between plants (avoiding overcrowding) can help prevent this problem.

Propagation Methods – Snapdragons are easy to grow from seed and will often self-sow volunteer seedlings in the garden although new plants may not be true to form of the parent plants. Started bedding plants can be easily purchased from many lawn and garden centers to set out in the early spring.

Using Snapdragons in the Garden Landscape

Companion Plants – Snapdragons do well with other cool-season annuals. Also, consider mixing snapdragons with other spring blooming plants for a cheerful spring border. Plant snapdragons between summer blooming perennials so the snapdragons will hold interest and provide color until the perennials fill in and begin their flowering season.

Seasons of Interest – Narrow foliage is attractive spring, summer and autumn but flowers are best in the cooler weather of spring and fall.

Uses in the Garden – Snapdragons are great in cut flower plant beds, containers, butterfly gardens, and deer resistant borders. They are charming plants often associated with cottage style gardens as well.

Other Uses – Snapdragons have long been a favorite garden play-thing of children – and grown ups. The rounded, tubular flowers resemble faces with two large lips and it is fun to gently squeeze the sides of the flower to see the ‚”lips” open like a mouth and then ‚”snap” shut again. Supervision should be maintained when allowing children to play with these flowers however, as all parts of the plant, including the flowers and seeds, are toxic if ingested.
