It was probably H. falconeri 'Damarapa.' Just remember that -- within a species -- bamboos vary in appearance depending on a lot of factors, and you might not get the same pronounced color as you saw in that photo. In addition, some bamboo that display certain colors or tinges (red/peach/pink/blue) do so when they are shooting and this fades as the culm matures. Finally, the Damarapa is only hardy to 20F, so it might not survive a Zone 7 winter.

I think you might be right, kudzu. Thanks.
