Hello fellow bamboo lovers. I need help with id. I bought a clump of what was called Wamin many years ago at a so cal bamboo society auction. It was described as max 20 feet tall, up to 4" culms, clumper. I was just doing a search for "Wamin" and all results showed it as "Dwarf Buddha Belly" with distinct bellies between nodes. Mine has been grown in a large tile crate box in zone 22 of Los Angeles, CA, for about 10 years and has never had a belly, even when drought stressed. It developed 15 foot culms within 2 years which yellow in the sun. It doesn't look at all like the photos of B vulgaris Wamin that I find. Any ideas?????
