Same here - pH of 8.2-8.4 (and a kH of about 19!), and I've got a couple varieties of val, several mosses, multiple varieties of crypts, java fern, anubias, bacopa, cabomba (green and purple), swords, tiger lotus, rotala indica, rotala colorata, broad leaf ludwigia, dwarf hair grass, lots of floaters (duckweed, hornwort, etc.) and I'm sure stuff that isn't coming to mind right now all growing in my low tech/low-medium light tanks. There are absolutely plants that won't grow in my water, but (at least in my experience) they're mostly the ones that aren't going to grow in a low light/low tech tank anyway. I don't know though that I've lost any plants that wouldn't have crapped out in my tanks due to light/ferts/cO2 regardless of pH.
