This blog entry is dedicated to helping you make Gold by Farming Heartblossom.
In the following image, you will see the route that I ran:
I was on a Tauren (200% Herbalism Speed) and a Druid (No dismounting), but didn't have the Bountiful Bags Perk - all of which can effect how much money you can make by doing this. Be sure to take all of these factors into account when trying to calculate your estimated Gold Per Hour beforehand.
I hope this accompanying write-up has helped to add clarification; and, as always, good luck!
