A short list of native plant blogs that I haven't yet had the opportunity to explore.
Deborah Small’s Weblog looks promising. She's in San Diego County. One of her areas of focus appears to the ethnobotany: In California sycamore / Platanus racemosa she talks about making tea from sycamore bark. There's some excellent photos there too.
foliasalviarum has more than just a salvia focus.
I find it interesting that both foliasalvaiarum and Deborah Small's site feature recent blogs on Datura. Perhaps there's a renaissance of appreciation for the plant that is commonly known as loco weed.
The Ojaigarden looks promising, but I haven't spent much time there.
