I hate this new format - no way to attach pictures to the original post from my phone.

At any rate, the 'different' leaves are mainly bottom left of the photo.

I see what you mean..the margins are wider on the left side leaves..I'll leave it to the experts about separating it..I wasn't able to post my pics WITH my post from my phone either..I wish they would address this issue..

You can attach photos from your phone IF you have them saved to some other hosting service. For example, I use Dropbox, and I have the app on my phone. So when I have a photo on my phone that I want to post, I can send it to my Dropbox account and save it there, then post it on the forum. A little cumbersome, but it works.

I can also download my photos from the phone to my computer by attaching them with the cord.... and I then save the photos to either the computer or Dropbox, or both.

windymess..thanks for the suggestion..photos post from my phone when I comment just not when I'm starting a post..there's no photo button to tap..it's inconsistent..sometimes works sometimes not..lately it's not working..are you able to post photos with the post when you start it?..

If it were mine, I would separate off the sport if you can do it so the new plant has a sufficient root system. It appears to be large enough that it's likely to have viable roots. It may revert right back to Stained Glass next year, but having more than one Stained Glass is not a bad thing. It might also keep the wider margin.

It appears to be slightly different from either Avocado or Cathedral Windows, 2 somewhat similar sports in the same family, but until it's more mature you won't be able to tell for sure.

I already have 2 'Stained Glass' but really like it so more is always better. This eye looks a bit more like the 'Cathedral Windows' I have than my 'Avocado' but it's hard to tell if it is the same or not. I'll plan to divide it once it cools down a bit in a month or so. I'm already gathering a long list of fall gardening work.

I didn't have a problem attaching photos from my phone to the initial post in a thread before the recent site "upgrades". I really hate almost everything houzz has done since they took over Gardenweb.

I think I would wait to see what it does next year, and separate it then, but that's just me.
