Firebloom and Kag whisFollow

My main is a NE Priest, she is lvl 38 now. I couldnt figure out what you mean exactly by "picking herb safely", 'cause till now, i havent seen a "safe place" to gather herbs. Even in ashenvale, there is always at least one mob near the herb.. Bad news, situation doesnt change for high skill level herbs :)

I have found fairly good amounts of Firebloom in Badlands. It usually grows in desert-like terrain and stands alone ( not near a tree or a hill )

Khadgar's Whisker can be found easily in Arathi Highlands. I also picked it up in Stranglethorn Vale. Look near the trees, it has a growing habit just like briarthorn.

Hope this info is usefull for you :)
Good Luck

Try typing the name of your herb in the search box to the left, then clicking on the map locations given. I've found that feature very useful for almost all the questions that start "where can I find..."

At level 38, you're on the low end for most of the locations for Khadgar's whisker, although with a buddy, the Alterac Mountain locations, Stranglethorn Vale, or the Swamp of Sorrows might not be too bad. If you're on a PvP server, the horde tends to be a major PITA in the first two locations, though.

Firebloom, your best bet is probably the Badlands, but you're going to spend a lot of time fighting. My wife is also a herbalist - we've had good luck getting her herbs by having me run through the area where the herb is, getting all the mobs to chase me, then she rushes in and grabs the herb before they return. As a paladin, it takes me forever to actually kill anything, but most of the mobs get tired of following me long before they do any real damage, especially if I have a Seal of Light up.

I was helping out with a qs ( I think called Princess) that took us close to a horde fort. There was tons of Khadgars whisk there. I really stocked up. Some sprinkles of Wild steelbloom which also went with me. Imo, that Wild steelbloom is so tricky to find or I just loose patience trying to get to it.
In reference to your comments about the STV and SoSorrows locations .. honestly I'm drawing agre when I try to herb these areas. Not only that going it solo i get beat up pretty bad. SoSorrows is a major haven for any herbalist but some of the items were out of my skill lvl range. My map had so many dots there when I visited, it looked like a poke a dot shirt design.
In reference to badlands ... well its just bad and rotten. Again going solo is like playing suicide. I only ventured in to the upper portion of Badlands and promptly turned around to herb some swiftthistle in Loc M / Thel.
Not saying your suggestion location(s) are incorrect or bad but out of my reach at this point and time.
Ty for above poster with the link. Some rank lvl number attacked to the list would have been great. Its frustrating to clear out a camp only to find you need more skill to pick a purple lotus.
I'll be checking out these loctions in the future. Ty for the listings.
