A seed worth growing
The classic sky-blue morning glory.
A fast heirloom climber with 4–5" sky-blue trumpets and creamy white throats over heart-shaped leaves. Flowers open in the morning and close by afternoon.
Vines grow fast through spring and summer, then bloom from midsummer until early fall, covering arbors and trellises or sprawling as ground cover. Easy to grow, and vigorous enough to reseed.
Flowers about 110–120 days from sowing; vines reach 120–180". Open-pollinated.

Know before you sow
Growing times vary with weather, soil and local conditions.
Speeds slow seed.
Or start 3–4 weeks ahead.
8–14" apart.
Lean soil, more flowers.
About 5–14 days, held at 65–75°F (18–24°C); warm days with cooler nights help. If seed is slow, nick the pointed end with a knife or clippers and soak up to 12 hours before sowing.
Sow 3–4 weeks before planting out, covered with 1/4" of mix (no light needed). Keep moist, harden off and plant out after frost.
1–2 weeks after your last frost.
8–14" apart, about 6" out from the wall, trellis or arbor.
Average, well-drained soil; it handles poor ground. Too much nitrogen or water means fewer flowers.
Full sun is best; tolerates part shade.
Give it a trellis, fence, arbor or stakes to climb.
Blooms are triggered by long nights, so vines grow hard through spring and summer and flower from midsummer into early fall.
Arbors, trellises, fences, containers and ground cover.
Grown as an annual. Vigorous and can reseed.
