Is this Alphonse Karr?
I picked these up from a disorganized nursery a a little while ago and I'd really like to sleep comfortably at night knowing that this is clumping bamboo. If I chose incorrectly and this species runs it'll be a nightmare. The person at the nursery told me it was Alphonse Karr, but he thought AK was a running species... where as my research told me it clumps. So... disorganized nursery + uniformed worker = a worried new bamboo owner.
Would you mind looking at the photos below of 2 separate plants and give me your opinion on species?
Plant 1: I split it so it looks thin and scraggly
