I recommend that you start on tiger lillies or another IP flower and then move on to sulfur (14), fruit(18), vegies (20), coal (21), poppies (28), red currents (34), blue berries (36), and nightshade(42) in that order. The poppies and nightshade are worth 1gc each in Irsis flower shop in C2, so please let us know when you will be harvesting these so that we can help you get them cashed out.
The numbers next to the items in is the recommended harvesting level....'harvestable (recommended level)'
If you take 20 will (that is an attribute) as soon as possible, your harvesting training will go quite quickly.
