Well Don your thread has certainly blossomed. That's the way it is with bamboo nuts- one thing leads to another. Anytime you change the microclimate you will likely change a plants response. Once again Brad is the microclimate guy.
bamaBamboo- the ground cover to the left appears to be vinca minor/major. There are about 5 or 6 varigated forms. The arrow shaped leaf to the right is similar to a climbing weed vine we have here, but I don't know the name.
Brad- Not only did the argenteo wake up, it exploded into several 1 gals that are thriving! The shoots on the prominens

I got from the ABS didn't look like bissetii, but hey, who knows. Time will tell.
Re propinqua. There is one shoot about 3ft from the mother plant that I could dig after it leafs out. It may be (not sure) a whip shoot, and I remember you are not a whipshoot fan, but I don't remember exactly why. I took some pics of the plant this morning, and I'll try to email them to you this evening for you to confirm the ID.
Markj- I really like the looks of 'luteo'. the colors are so monochrome, and the sulcus stands out sharply against the green. I'll be there this weekend to pinch a piece of yours

. Just kidding but would like to meet you and see your collection if I'm ever in those parts.
