Hello Tropicsman!
My wife's family lives on the South East side of Wichita. We head down that way about once every two months! I will send you a PM so we can talk, I would love a tour!
Red Margin Bamboo is also known as Phyllostachys rubromarginata. It is very vigourous and supposed to get the tallest in my area. I have two more bamboo beds I want to add, but didn't want to dig another bed this year
PS: the pics look great!
