There was a time in Bangalore when finding exotic herbs involved a trip to some remote farm in Ooty and finding out their supply route to Bangalore.
Thankfully, much has changed.
Look what I found at Namdharis..namely the one on M.M road, off Mosque Road, Fraser Town.
I felt like a kid in a candy store! Recipes to what I've used them for, to follow!!
I recall seeing a collection of the same, in 1 MG Road, opposite Taj Vivanta as well, in case that is closer to you.
PS. I also found thyme, but I forgot to photograph it. Got all the herbs + salad leaves for Rs. 105
