I'm growing them in containers, so the issue of seeds isn't so much a big deal. But I can see what you mean if you've got a small plot with them growing in the ground... they could proliferate before you know it.
They do indeed have a subtle flavor. But if you slather them onto whatever you're eating, believe me--you'll taste the onion-like flavor. And besides, they are packed with nutrients so the more you eat the better. Just three grams contains 3% DV of Vitamin A, C, in addition to a number of other trace elements like calcium and iron. There's supposed to be some anti-inflammatory properties as well as anti-oxidants. I suppose you need to eat quite a lot of them to get a decent jolt of that in one day. But whereas nutritional advice labels all focus on the Daily Value, there is something to be said for long term ingestion of certain nutrients in small amounts (not captured in those labels).
