we don't hardly even eat them...
we had a border/low spot at the bottom of the north garden where Mom wanted to plant sunflowers. she did but the chipmunks kept eating the plants/seeds so she came up with the idea that she could put down the tops of chives (including flower heads with seeds in them) to deter the chipmunks. it didn't work, but we managed to get sunflowers to grow there a year or two...
in the meantime those seeds sprouted and grew and we left the plants to grow because i like the flowers and the bees do too.
a few years later as the horsetail invaded it was impossible to get it removed entirely from that garden with the chives protecting the horsetail roots and me hating to dig up the chives because the smell of the roots makes me gag.
finally i just had to do it... dig up that entire edge along the north garden and hunt down all those roots from the horsetail.
here are some pictures from the red patch (what it was called before it became the north garden), me hunting down horsetail roots and other bits i could find:
pretty flowers!
notice how big that patch of chives is at the right of that garden? that's not our only patch of chives either, we had several others...
redoing the edge, hunting horsetail... that pile there is stacked up chunks of chives which i left out all winter so they could get some rot going and frozen and weathered in place there in that stack...

i have another picture someplace (it may not be on the website) where there is some snow and ice there and that pile looks like a face peeking out of it...
but they sure were pretty when they bloomed (the two purple flower edges in the background)!
