About the genus

Antirrhinum is a genus of plants in the Plantaginaceae family, commonly known as dragon flowers or snapdragons because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are also sometimes called toadflax or dog flower. They are native to rocky areas of Europe, the United States, Canada, and North Africa.

In the garden

Antirrhinum majus 'Monarch Scarlet' (Monarch Series) is a named cultivar of Antirrhinum majus in the family Plantaginaceae. The plant forms a well-branched clump with deciduous leaves and produces flower spikes through the summer; in the UK its flowering season runs from June to September. Position the plants in full sun or partial shade on well-drained soils; they will tolerate chalk, clay, loam or sand and a wide range of pH from acid to alkaline. A south- or west-facing, sheltered spot reduces exposure to strong winter winds and helps protect tender shoots. The cultivar is rated H3 (borderline) for UK hardiness, so in colder gardens consider a frost-free mulch, siting against a sheltered wall, or lifting containers to overwinter under cover. Use 'Monarch Scarlet' where upright flower spikes are wanted: bedding and borders, city courtyards, patio containers and wall-side plantings. Stems also work well as cut flowers. Planting in groups or alongside other early-summer perennials provides structure through its June–September flowering period.
