Having all the branches growing in a whorl is highly undesirable. The reason is, the trunk will thicken badly in the area of the whorl and you'll be left to wonder about how to deal with the reverse taper of the trunk (as in layering it off right below the swelling). If your intent is to keep it in a pot, I would remove all but the one branch that best compliments the formative structure, with the thought that it's eventually going to be the new top - when you sever the main trunk (to give the plant some taper) immediately above the branch you choose as the eventual new leader.

Some of the eucalypts make very nice bonsai, but I'm trying to envision what the growth habit of that particular species might be like. Don't let that stop you from having fun with it, though!

Yep, the only thing I was sure of was that I was wrong. At least that's right! Thanks for the response, Al. You know I'm always having fun with the plants!

Just realized I never indicated its' species, E. polyanthemos.

These trees are hardy here, but not at all common. Not even sure if the few I've seen are all the same species, but generally, they are unruly, gangly, gnarly. I have no experience with them either.

Your future vision is more acute than mine, even if we are the blind leading the blind on this particular species, so if you don't envision a result that looks like a little weeping cherry or willow (except for the Eucalyptus leaves,) it's probably not possible.

I have no fantasies that this would be a proper bonsai, but seems like it could be a cute little curiosity. Will post pics of whatever torture I devise for this sad little guy... My Mom has even quit asking if she can have it for her yard.

If you want a little weeping tree, get a Ficus pumila and train it to an upright form. It's branches will be innately pendulous. ;-) Have fun!
