Dear Jim and Tsuh Yang, I have grown water spinach, Ipomoea aquatica, in the vegetable garden, so it doesn't need a lot of water. I have always been confused by reports that "morning glories" are poisonous. Houttuynia cordata --- this has been a menace in my herb garden where I made the mistake of planting it. It is very invasive, smells awful (not nearly so nice as cilantro which it is supposed to resemble) and cannot be weeded out. I resorted to painting each bit that sprouted, with an herbicide, but next year will tell the tale. On the subject of edible alliums, Allium tricoccum - ramps or wild leeks - are a seasonal folk food in parts of West Virginia. I have eaten them boiled and could hardly recommend them except to those folks who are fond of great chunks of raw garlic - not exactly the same taste, but the same kind of intensity. But I hear that they are being served as a delicacy in fine restaurants. Does anyone know if it is possible to cultivate these bulbs? I have a source and would like to try. Dell
