How to grow Morning Glory?

There are several different species of Morning Glory, the vining types in the genus Ipomoea and the dwarf/bush types in the genus Convolvulus. These relatives of the sweet potato are usually grown for their showy trumpet shaped blooms in a variety of colors and patterns. Most are tender perennials grown as annuals. These plants shouldn't be confused with Convolvulus arvensis, which is an extremely noxious weed commonly known as Wild Morning Glory or Hedge Bindweed.

Different species of Morning Glory are native to different parts of the world. The vining types are native to tropical and subtropical parts of the world. Bush and dwarf types are native to the Mediterranean.

Seeds
Seed Viability: 2 - 4 Years
Morning glories easily cross-pollinate, so if you want to save seeds its best to grow only one variety or isolate the varieties. The plants generally self-sow and can easily become a noxious pest, so its best to not let the seed pods ripen to the point that they release seeds. Remove the flower heads before the seed heads shatter and dry on a screen. Crush the seed heads to release the black seeds.
The seeds are poisonous, so they should kept out of the reach of kids and pets.
