How would one attempt to find this species in the wild. I have been surfing the net for good retailers, but in my opinion, 8 dollars for a 2inch by 2inch square of "water weed" is a bit expensive (I also have to pay for the shipping and handling). I did some research and found out that this specific species actually prospers in the waters of the Pacific North West!!!! Would any one know good spots where i could find this plant? I live around the portland area
