I HaveC. quadrangularis
SQUARE BAMBOO (HOUCHIKU) 25' max height 1.50 max diameter 15 degrees f. minimum temp . Culms are square in cross section with rounded corners, especially on large mature plants.

rb... what size plant are you offering? Is it a clumper type? Have a pic I can see of what your offering? Sounds interesting...have not read about this one...but will look into in now :-D
Thanks

It is a runner,been in a 3 gallon pot for about 6 weeks.1 culm about 4 feet tall.Give me a email address and I will send you a picture.rbkelso@academicplanet.com
I have a larger pot that I could cut off a section if you wanted more culms but the one already potted has taken root.

Sorry rb... got another offer... will be dividing a large Buddha once the rain stops... we got 5 inches over night...still raining now. Had to drain 8 inches from the pond...fish were nearly into the yard :-0

The divisions should cook in pots for a months before I send them out. I'll post again with pics when they are ready.

Thanks for the Trade Fred :-D I'll be sending this one out Friday.
Take care all
