| Common Name | Snapdragon |
| Genus | Antirrhinum |
| Species | majus |
| Family | Plantaginaceae |
| Life Cycle | Tender perennial, grown as hardy annual. |
| Tray Size | 8 |
| Plug Care | Transplant within 2 weeks of arrival, or bump up into a larger cell until you can transplant. |
| Netting / Staking | 1 layer of support netting |
| Temperature Range | Snapdragons like it cold, especially when young. Short drops to 20F or colder are tolerated well. |
| Spacing | Plant in clusters of 2-3 seedlings, with 6" spacing. Plugs are multi-seeded with this in mind. |
| Soil Preference | Well drained, generally fertile soil. |
| Day Length | Facultative long day |
| Pinching | Pinching will produces more, but smaller stems per plant. I prefer to not pinch, resulting in taller stems with larger flowers. Use a wider spacing when pinching. |
| When to Plant | In autumn, plant 3-4 weeks before first frost. In spring plant 3-4 weeks before last frost. These cold hardy plants prefer frosty conditions to hot conditions. Plant at the same time as Stock and Campanula. |
| Harvesting | Harvest when 1/3 to 1/2 of the buds are open. |
| Post Harvest Care | Harvest into a holding solution. Snapdragons are moderately sensitive to ethylene. |
| Diseases / Insects | Generally easy growing. Rust is an issue in some environments. Harlequin bugs love snapdragons in summer. |
| Bailey's Notes | When planted in fall or late winter, snapdragons will reach 3-4" easily. Different series bloom at different times and you can extend your harvest window by planting several series at the same time. |
