So why would I post a picture of this particularly common and often unwanted bamboo? Because it's growing smack in the middle of Zone 4, just west of Minneapolis. It is in the Minnesota Landscape Arboretum's Japanese Garden. It dies back to the ground each winter, but comes back vigorously enough that even here it has to be controlled or it will spread beyond where it's wanted. It's only 4-5 feet tall, but has been surviving and spreading for quite a few years. I would love to see if a start of the P. bissettii that our friend from Needmore Bamboo in Indiana says is so hardy would grow here. Anyway - the picture:

P. aureosulcatus
