I started off bog gardening because of carnivorous plants, but now I find I'm really getting into some of the other plants from a "true"* bog/heath ecosystems. Each time I walk in places like the NJ Sand Barrens, Green Swamp (NC) or in Apalacicola (FL) I'm aways in awe of all the unusual plant species all around me. I've currently got many species of native orchids including Platathera intergrilabia, P. Ciliaris, Pogonia, Spiranthes Cernua, Swamp Pink and Calopogon. I've also got both species of native cranberry, leatherleaf, New Jersy Tea (dwarf), and bog rosemary.

Are there other suggestions out there for really great North American bog plants? I'd especially like to know if people know sources of where I could get them too. It is a shame that few nurseries specialize in this.

*By "true" bog, I mean an acidic, sunny, sphagnum covered, low-nutrient environment.

Sounds like you already have a very nice list to me. There are other Platantheras that are showy like dilitata, blephariglottis, cristata and some that are less so but still worthy like clavellata and flava. I also grow some Dactylorhiza which are europeans.

Planteck sometimes has some interesting things but you have to baby them to get them established. Try Bill Mathis at Wild Orchid company. Also Meadowview is the best one left for Carnivores. Dean Cook sometimes has interesting things at Cook's Carnivorous plants as well. Keep searching (I do), you never know what you may find. Good Luck!
