Morning Glory Vine planting information:

NOTE: Check local planting regulations before planting, as many varieties of morning glory are considered invasive in some areas (including Arizona). See the last section of this article for more information.

When to plant: Spring after the danger of frost is passed.  Plant seeds directly in the garden once soil temperatures are 65 degrees or above or started indoors 4-6 weeks before the final frost date for your area.

How to plant: Scarify seeds and soak them for 24 hours before planting, direct sow or start indoors and plant young transplants.

Where to plant: Grows in full sun or partial shade. Morning Glory plants prefer full sun, so pick an area with direct sunlight for 6-8 hours. Morning glories thrive in average to poor soil, where they will quickly climb trellises or fences.

Size and spacing details for Morning Glory Vine:

Plant seeds or transplants 8-12 inches apart (20-30 cm).

Grows 15 feet (4.5m) tall and 1-2 feet (60-90cm) wide.

Morning Glory Vine growing tips:

Morning glories begin to flower after the summer solstice when daylight gets shorter and continues through frost. Each flower only lasts a day; it opens in the morning and closes in the evening.

It attracts bees, butterflies, hummingbirds, and other pollinators. Morning glory vine is easy to grow & maintain.

Considered invasive in some areas, grow in a container to keep the plant from spreading to other areas. See the section below about growing morning glory in Arizona.

Is Morning Glory Vine illegal to grow in Arizona?

Effective January 4, 2020, most native morning glories have been removed from the list of noxious weeds and can now be sold in Arizona. However, according to the University of Arizona Cooperative Extension Office,

Caution should be used when planting morning glories as
they were previously prohibited for a reason; they can get
out of hand quickly and become a nuisance or drastically
impact a backyard garden or agricultural crops. In addition,
morning glories are very difficult to eradicate once an
infestation has been established. However, if you like the
appeal of the delicate and colorful flowers in your garden,
you will now be able to buy them from your seed or plant

Varieties of morning glory that are still classified as either Class A, B, or C Noxious Weeds include:

  • Tall morning glory (Ipomea purpurea)
  • Grannyvine (Ipomea tricolor)
  • Ivyleaf morning glory (Ipomea hederacea)
  • Three-lobed morning glory (Ipomea triloba)
  • Whitestar morning glory (Ipomea x leucantha)
