Wild Onions - have a single, long, slender shoot. Similar to rushes (wetland plant) the have a slightly larger bulb than a ramp, and a similar but more mild flavor than the ramp. Ramp> wild onion in my opinion.
Wild onions come up much earlier than ramps. Heck drive past a corn field now and you will probably see many wild onion sprouting along the field/woodline boudary. Both are abundant here in MerCo.
Leeks, have a whorled leaf and a thick base for a bulb.. maybe 1/2 - 1" diameter. I have never picked leeks.
Morels are sprouting in greene/wash counties now
I expect another week at least before we see them here.
But if anyone stumbles upon them in NW PA, let me know
