There are probably some collectors near you who can get you some bamboos. I think for your climate, hardy tropical clumpers may be the most rewarding so you could look into getting some bamboos in the bambusa genus which are mostly hardy to zones 8 and 9. Dendrocalamus bamboos might work too for you, but will get winter damage when it gets several degrees below freezing.
There is a bamboo nursery right in Houston who sells bamboo online so you might be able to visit them directly since you are already in the area, but I would suggest figuring out, and doing some research on what type of bamboo works best for your needs before buying all kinds of plants. If you are planting runners, you probably don't need any more than 1 plant as they probably run like crazy in your climate. Clumpers can also be propagated easily with culm node cuttings so there shouldn't be a need to go crazy on them as tropical clumpers grow at some very impressive rates. http://www.houstonbamboonursery.com/bamboo.htm
Thank You very much for pointing out that Houston Bamboo site. I dont know why it didnt occur to me to search Houston. Good lookin out.
What do you mean by "cane"?
Alan, long before we moved to this property there was sugar cane grown on it. Rumor has it that the warehouse in the back was at one time used to process the cane. This comes from some of the older folks here in the neighborhood. We are not that far from Sugarland Texas which did at one time produce sugar for Imperial Sugar.
A few years ago, about 10 to 12 miles away I noticed a guy planting something around his fence line in an attempt (I believe) to obstruct the view of his property from the street. Its a busy intersection. I thought about him (or her) yesterday after signing up here at this forum and reading about the bamboo. Its on the way into town and I needed a haircut anyway so I drove by there. It does appear to be a clumping bamboo. I will snatch a photo in the next day or so, so that I can show yall. I am thinking about asking him if he would share some of it come Spring time. Spring time is the correct time to do this, que no?
