Last October I planted leeks and fennel, and it's pretty obvious that I didn't harvest things when I was supposed to. Neither plant go particularly big, so it's probably just as well that I let them go to seed and try again in the fall.
Leeks have pretty white puff-ball blooms similar to onions which is unsurprising since both are in the allium family.
Fennel have yellow blooms which remind me of Queen Anne's Lace.
I think the two of them contrast nicely with each other, and I have a hunch that a field of these would be absolutely divine as far as color and texture go. It wouldn't hurt to throw in some purple though.
