From the Sticky in Trade Skills, under the herbalism section, comes my own guide:

Mountain Silversage:

My favorite herb, personally, it fetches a very nice price at the AH, and is rare enough that few people can find much of it (but I know some good spawns :-D). Mountain Silversage is used for multiple flask recipes, for Major Healing Potions, and Elixir of Mongoose. Amazing, ain't it? My best spot for it: Un'goro Crater. Like Wild Steelbloom, it grows in high, rocky areas; circle the outer edge of the crater looking on your minimap for the yellow dots to appear. It takes a while, as spawns are spread out, but you can find a lot like this. Another good spot is in Felwood; around the green oozy lake bridge, there is a rocky part north of it (near where the Warlock quest guy is). Occassionally there is a spawn there. There's also spawns further north, where the satyrs that drop Felcloth are found.
