I mostly only do herbs and calquat. Calquat is mad cheap for xp at around 2 gp/xp. Trees are too expensive for me, but fruit trees are manageable. I suggest curry, pineapple, or papayas. But if you want fast xp, do either snaps or torstols, palm trees, calquat, and magic trees. If you need further info, Grimy's spreadsheet is always helpful. http://spreadsheets.google.com/pub?key=tvyX6CDj7qNBx5xIA5ShA-w&output=html Edit: to reply to your most recent post, maples and palms are around 9 gp/xp. Always do calquats and herbs still.
