Here are a few more pics:
This one gives a good idea of the glaucous leaf color:
Here are a few more seedlings. Sorry for the poor quality. A new batch of 10-12 seedlings have just sprouted and I was trying to show the cotyledons of several at once. Didn't work out too well.
I'm pretty much leaving them grow wherever I find them, as they are in a variety of habitats. Some seem to be doing OK. Some seem to be struggling a bit. These can be side by side. All seem to be growing rather slow. None seem anywhere near ready to bloom.
The last batch of seedlings are in mostly full sun. Unfortunately I had pulled up numerous vines that were doing well earlier in the year, as I was afraid they were aggressively invasive and didn't want them to get out of control. Apparently I did not need to worry so much.
Still hoping for an ID.
