Was just reading your post while catching up on the thread. I had just done a search, and found an article on willow.
Thanks for confirming what I just found!

Onion bottoms...are these like grocery store onions that have the hairy root still attaches that you have sliced off and started with root powder? If so, I think I could do that too!
“My celery just sat there and got funny looking.”
Are you saying you put root powder on a cut off celery? I have just been trying that, and while it started generating roots, it hasn’t done anything else. I’ve been wondering if I should let it sit til Kingdom Come, to see what it does, or if I should give it up as a bad job. The heck of it is, that the celery stump has generated a LOT of very strong looking rootlets, so it has been hard to just give up on it!
I’ve had real good results with romaine stumps. I planted my first experiment and it is growing some gorgeous leaves! The second one has generated some wonderful rootlets and is starting to grow the leaves. I think in a few days I will plant it as well.
Hmmm, I have Romaine. Great idea. The celery that looked funny is now helping out the compost heap.
