I'm 5a zone. Muncie, IN and yellow groove bamboo has been totally hardy here. I mulched it with leaves the first year, but since then I've been too busy.

Here in Columbus, I am currently growing 10 species of bamboo for about 2 years now. There is probably over 30 different species you could care for successfully.
Arundinaria gigantea
Phyllostachys aureosulcata and cultivars
Phyllostachys bissetii
Phyllostachys nuda
Phyllostachys rubromarginata
Fargesia sp.
Many Pleioblastus sp.
Those should do well with proper care.

Hi I live in the Cleveland OH area. I have Phyllostachys aureosulcata (Yellow groove) and its also in my Japanese garden. Another cool plant for Japanese gardens although it is not bamboo is Horsetail rush, do you have that in your garden? I know someone near me that has Phyllostachys Aureosulcata it is a mature old grove and the culms are 3 inches thick! Very cool. Mine are small because they are only 3 years old I'm looking forward to when they become like my neighbors.
