i know the subject line sounds a bit off topic, but i promise i'm talking about some of our plants... i was on one of my infrequent trips to chinatown today and i saw some leafy vegetables in a sidewalk stand that looked somewhat intriguing. they were somewhat triangular leaves along a stem. i thought to myself, these look like Ipomoea leaves. i asked someone what they were, and she said they were sweet potato leaves! in my infinite ignorance, i never knew that sweet potato leaves were edible. of course i had heard of water spinach, which is an Ipomoea, but a totally different one. also, i have read that in china there's a garlic variety that produces a bulb with a single clove. does anyone know anything about this garlic? does it taste distinct from the "regular" kind? ======= tsuh yang
