For those of you who've asked where to get seeds in the U.S.

My first purchase was from Cary at lakebiofuels.com

the guy has thousands and thousands of seeds available. you can buy in bulk too.

if your ambition is a bit smaller, echonet.org out of florida will sell you a pack of about 13 seeds for I think $5.00. not bad to just check things out.

and I've had 95% germination with both varieties of seeds from these guys.

echonet.org also donates some percentage of the proceeds to charities, I dont know which.
