How to Understand & Appreciate Bamboo : Understand Large Types of Bamboo

[classiclistener01]

@expertvillage - I have this very tall, fast-growing bamboo that clumps, but, it also spreads with rhizomes. It begins growing in April and can get well above ten feet by mid-summer. Would you have any clue as to the possible species of this beautiful, clumping and spreading bamboo that grows wild in New England, USA? Thank you! :)

18 feet in one year? I thought it was like 1 foot a week
