I just returned from a trip to Vietnam and Cambodia where I became fond of a vegetable called "Morning Glory Spinach". I believe the botanical name is Ipomoea aquatica. Can it be grown in East Central Illinois? If I grow it in my garden, do I need to worry about it becoming invasive like the common morning glory that invades so many farmers' fields? Any suggestions as to where I can buy seeds? Thank you!

Jean, so good you asked this question before planting. Ipomoea aquatica is on the Federal Noxious Weed List. http://www.aphis.usda.gov/import_export/plants/plant_imports/downloads/RegulatedPestList.pdf so do not plant it. there are plenty of good leafies to plant that do not invade. Malabar spinach is a spinach alternative as well. so happy you asked this question. first. i wish more gardeners would be as thorough. Sandy

I'm also very glad I asked. :) My first clue was that the seeds weren't offered by any of the major US seed houses.

Malabar spinach is a great suggestion. I'll enjoy harvesting salad greens that can withstand summer heat in East Central Illinois. Do you have any other suggestions for summer leafies?
