I have grown morning glories before. You need to have some sort of lattice or a chain link fence for them to grow on. Dig a trench in front of the lattice/fence, mix up some fresh garden soil with a few hundred seeds in the wheel barrow, fill the ditch with the dirt and seeds, then water it every morning. In a week, it will sprout like a Chia caterpillar. Worked for me... It's something you want to do in the spring, though.
If they have dirt, water, and sunlight, they will grow. The quality of those elements will determine how healthy and productive the plants will be, but they grow like weeds. You will still need something for them to climb on, though.
They are twisty, climbing anual vines that will reach up to 15-20 feet high if given the proper conditions. And they have flowers.
Water them, have well drained soil and lots of sunlight. That's really all you need to know. They get really, really big. Which means they need a lot of water every day.
