Growing Guide: Antirrhinum – Snapdragon

Annual plants, sometimes grown as biennials, and commonly marketed as bedding plants.

Situation:

Especially in beds with other annuals but sometimes combined with perennials. Require full sun.

Soil:

Any reasonably manured garden soil.

Propagation:

If grown as an annual, the seeds are sown as early as February in a heated frame or greenhouse. Seedlings are pricked out, the tips are pinched out once, and they are slowly hardened off in mid spring. When grown as half-hardy annuals, they are sown out of doors in late summer or early autumn and, after having been pricked out, the seedlings are transferred to a frost-free frame or greenhouse. They will flower as early as mid spring.

Antirrhinum majus: Height 20-80 cm; flowering season, depending on method of cultivation, between mid spring and early autumn. Flowers include all colours, except blue. There are tall, medium and dwarf varieties; the open-flowered forms are called penstemon-flowered.
