Don't know yet if it will keep it's stripes after cutting. But I do know that the stripes last
! The culm in the bottom picture has had these same stripes for 2 years now! But this is the first year, since I started, that I've had any culms large enough to use for lumber. They'll have to be tagged cause they have to feed, from the ground, for 2-3 years before they're strong enough to use.
Nice choices in that trade, JaNan
! Nuda & Yellow groove are Super!
The Nuda shoots start out near-black, in spring, and switch to dark-bluish-green as they grow! Height is around 25-30 feet but in your zone, it could get to 34 feet! The culm sheaths are black/reddish-purple and get to 1-2" wide. It's USDA 5-10 and hardy to -10*F. Also, the culms have bright white rings at the nodes. Should be Awesome!
The Yellow Groove is even better! In zone 7 (or higher) it'll get to 40 feet tall with occassional zig-zag dark-green culms (of course with the vertical yellow grooves). That one's hardy to -10*F too (USDA 5-10). The culms will also be around 2" wide.
Both are great for setting up a privacy wall with

If they were mine, I'd be a little nervous about planting outdoors, right now. I know Aureosulcata doesn't like being over-watered & late fall is usually very wet. Getting precise care info, for each species, is hard to do. But definitely give it a shot! Most bamboos like a rich soil with fair drainage. I used 40% compost, 40% garden dirt, & 20% sand. For fertilizer, since bamboo is a grass, any good lawn fertilizer will work great!
Be careful though. Both Nuda & Aureosulcata are runners so, when you do put them outside, you'll need a bamboo rhizome barrier to keep it from getting into everybody else's yards
! Sorry
. The thought of bamboo taking over whole cities just gets me going, LOL!!
Better use large pots to keep them indoors over the winter. The runners can get Very long. And you're right! Watering is a seasonal thing. They'll need more water during the hot months & less when it's cold.
Hope that helps
