I ordered my bamboo from oregon, perhaps not wise to pay that shipping but i wanted what i wanted.

After you look around at this sight a bit at all the pretty bamboo, go to the price page to help ou choose.
I knew i lived in zone 6, my bamboo had to reach two stories tall to shade the sw side of my house, it had to tolerate full sun,....etc. All of this is listed on the price page. I had to go to the individual pages to see how large the canes were, i didnt want thin weeping canes (not enough space). In all honesty, if i could find a local place after I knew my choices I would go there but it is a wonderful place to decide which one you want.
