Golden Bamboo

Here's a page with info on the bamboo the bunnies agreed to order for the pandas. I'm not sure how to feel about this plant personally. Granted, the page mentions potential growth to 30 feet in height, but it seems to imply that the plants normally grow much less than that. So, do you think this could somehow be a safe bamboo? I swear, if it looks like it's heading for 30 feet, I will lock those pandas outside until they've eaten it down to a decent height!
