Garlic

Yes from the cloves - I have never tried from seeds but I think they take a fair bit longer to get to the stage where you get an edible bulb. Others will no doubt let you know.

The first year from a bulbil you should get a "round"... it's what the single clove garlic some supermarkets sell is.... I'm going to try growing a poatch of it, if it works you're looking at individual easy to use cloves... if it doesn't, all it's cost you is a couple of square feet for a season.... I've started some off in pots and some of it's up already... Never seen proper seed off garlic (though it must produce some under certain circumstances sometimes) but I live in hope....
