Shane and I will be there. I've gathered an assortment of extra plants to bring, including some Riccia which I think someone requested.
I'm looking for Ludwigia inclinata var. verticillata "Cuba." I thought I had it, but based on my research, it's Pogostemon Stellatus.
I'd also be interested in Ammannia gracilis or Ammannia latifolia, and Hygrophila corymbosa 'Stricta'
