I have some MOSO from earlier this year.
CJ

What would it take to get some seeds? I have some stuff to trade but it may or may not be of interest to you. What types of plants are you interested in? I have some cacti seeds and some joshua tree seeds. A lot of vegies and some other stuff. Let me know

send me a list clutedad@nc.rr.com I'm sure we can figure something out. Here is a pic of the result of germinating MOSO earlier this year. Same batch of seeds I will send you.

July MOSO sedlings... they are twice this size now and I will be seperating them into single 1 gallon pots real soon.

ocimun nate..

you can find a some seeds on ebay that are pretty affordable
look for a thread here in which some of us posted their experiences with reputable sellers on ebay

with all these Moso seeds getting planted all over the USA, we'll have some great Moso forests in a few years. Should really help people appreciate bamboo.

ocimun nate-
If you buy seeds on eBay, you need to know two things:
1) Importing seeds from sources outside of the U.S. is prohibited by the USDA (without a permit), and they could be seized coming into the country.
2) Bamboo seeds lose viability pretty quickly, so it would be good if you could determine from the seller that these are recent seeds.

If you do buy on ebay I can assure you that pontos33 sells viable seed.

I read on the usda page that they have amended the importation laws to forbid the importation of bamboo seeds without documentation and certification etc as kudzu stated. All of the sellers I looked at on ebay were out of country so I nixed that idea in favor of trying to find someone stateside.

ocimum_nate-
As you may be aware, bamboo seeds are not readily available because the plants flower only infrequently (like once in several decades). Nonetheless, there are so many species that seeds do become available...and hopefully it's something you want, when they do. So keep checking eBay. Things are always popping up.

ocimum_nate,

This has been discussed greatly before. Lots of things are banned from being imported, yet it still comes into the country uncontested, and I'm not just talking about boo seed.

Unless you are lucky enough to know a major grower that is willing to sell or part with seed or have a friend that has one that is flowering the chances of you finding a US supply are nearly impossible.

On top of that, even the sellers on eBay that are be selling boo seed, even though they are in the US, probably have bought these seed from overseas.

Therefore your best bet would be to contact your nearest ABS chapter, become a member and go from there.
