Proper ramps are a different species and have very wide leaves and look more like lilies growing than domestic and wild onions like the ones in the OP's yard (though they are all in the same family). Pretty sure ramps only thrive above a certain elevation and in certain exposures.

For those that haven't had them, I find them to be like a cross between a mild onion and mild garlic. A lot of flavor without the heat some onions and garlic have. But yes, good eating and good to cook with.

I'm from NC's ramp central area up in the mountains. Country folk take ramps dead seriously. The fine bladed wild onions are apparently an native american food staple.

If any of you are in NC come early may. https://visitncsmokies.com/attractions/ramp-festival/
