Hollow City is where you want to farm. Go there at an off time as there are usually a few PCs farming. But the nodes respawn quickly and you can just keep making laps of the city and fill your bags up. Bolt Escape can help, so can a horse.
Barring that, Keen Eye is essential to me for Alchemy Farming, esp for Mountain Flower and Columbine and a few others. In 4 months without using Keen Eye I probably found 30 or 40 reagents. Once I turned that on, I now have multiple stacks in just a couple of months. For the record, I don't farm alchemy mats, I just pick them as I go along from place to place.
Harvest Map is an addon that will track the Nodes you discover, and then show them to you on your map. You can use this to plan a route for your farming runs through a zone. Note, you have to discover the node first for it to be marked on your map.
