Wisteria
Wisteria sinensis
A single wisteria in Sierra Madre, California covers over an acre and is recognized by Guinness as the largest blooming plant in the world — over 1.5 million blooms per spring.
How to care for wisteria
Plant native American wisteria (Wisteria frutescens) instead of Asian species — Asian wisteria is highly invasive and can crush structures with its mass. Prune twice yearly (July and February) to control growth and encourage flowering.
Garden uses & design ideas
Best garden use
Give it a trellis, arbor, fence, or wall where vertical growth can soften hard edges without crowding nearby plants.
Pair it with

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 5-9 before planting. Use the garden planner to test spacing around its mature size: 10-30 ft long.
Gardener note — Double-check local invasive, edible, and toxicity guidance with your county extension office before planting around pets, children, or natural areas.
