For those needing some assistance wading through the lengthy seed list: as usual, I have put my online version up at http://www.robsplants.com/plantlinks/nargs/ . It may help you whittle down the list - I use it every time to make my own selections. In any case, happy seed-selecting and -starting :-)
note: I had no luck myself starting some of the seeds I submitted to this year's swap, so you may wish to stay away from them, even though they are still available:
* Viguiera stenoloba
* Maurandya antirrhiniflora
* Turnera ulmifolia
All others should be OK. In fact, I ordered some of my own seed for Cassia nemophila in the surplus round, as extra insurance, since I lost the mother plant in the big freeze here in Texas.
