That was two years ago.
We planted one, maybe two plants. So we had heaps of leftover seeds.
I learned from Making It: Radical Home Ec for a Post-Consumer World that you can grow broccoli as a micro green. Basically you plant a whole bunch of seeds really close together, wait until they've got four or more leaves, and then cut them with shears and toss then in your salad.
|The other side isn't empty--those seeds were from a packet that didn't sprout.|
So not much to lose.
You can do this with other seeds, as I recall from the book, but I don't remember which ones. Anyway, it's fun and easy, and it's nice to have something growing on the windowsill.
