Re: Rhode Island No specific Aquatic Plant club, but do check out TFSRI - we've been getting more and more plant folks, and I was very impressed by the number of plants at the last auction.
There has also been an increase in the number of plant-related lectures, too.
There is another TFSRI auction March 19th. Search TFSRI (Tropical Fish Society of Rhode Island) for more details. Meetings are easy to get to (I'm in MA, but the RI meetings are much easier to get to than the BAS ones for me), and its a low key, friendly group.
