Morning Glory

Ipomoea purpurea

Morning glory flowers open at dawn and are closed by noon — the rapid wilting is genuinely programmed cellular death, not dehydration. Each bloom lasts a single morning, but a vine produces hundreds across the season.

Care guide

How to care for morning glory

Soak seeds 24 hours and nick the seed coat before sowing — germination is otherwise slow and erratic. Plant after frost. Self-seeds aggressively — pull spent vines BEFORE seed pods open or you'll have a perpetual patch.

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

Sunflower, Corn, Squash (vertical pairing) 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 2-11 (annual in most zones) before planting. Use the garden planner to test spacing around its mature size: 8-15 ft tall (climbing).

Gardener note — Double-check local invasive, edible, and toxicity guidance with your county extension office before planting around pets, children, or natural areas.
