Snapdragon
Antirrhinum majus
Squeezing the sides of a snapdragon flower opens the 'jaws' — a kid-favourite party trick that's also a clue to the plant's specialized pollination: only heavy bumblebees can force the throat open, so smaller bees can't steal pollen.
How to care for snapdragon
Plant in fall in zone 7+ for spring bloom; plant in early spring for May-June bloom in colder zones. Pinch tips at 4 in for branching. Deadhead spent spikes for a possible second flush.
Garden uses & design ideas
Best garden use
Use it where you want fast seasonal color in containers, walkway edges, or gaps between slower permanent plants.
Pair it with
Pansy, Sweet alyssum, Lobelia make easy companion choices because they share similar light, water, or visual texture needs.
Layout tip
Match it with full sun exposure, place it in a moderate-water bed where soil can stay evenly damp but not soggy, and check USDA zones 7-11 (cool-season annual) before planting. Use the garden planner to test spacing around its mature size: 6-36 in tall (cultivar-dependent).
Gardener note — Double-check local invasive, edible, and toxicity guidance with your county extension office before planting around pets, children, or natural areas.
