In Feralas, I found three [Sungrass] nodes right ontop of eachother at 55,74. Along with a [Khadgar's Whisker].
Helpful to those leveling herbalism and/or need Sungrass. There is also one around 43,12.
I'll edit if I find anymore hotspots.
[MORE] Purple Lotus - 59,57
Sungrass - 58,55 / 57,54 / 51,47
Golden Sansam - 57,48
