In terms of ten new plants, they can be divided into two kinds in total: those generate XP for other skills (namely besides Farming XP) and those which produce something after a harvest.
For the second kind, it refers to wonders of nature, such as fly traps. They can help you earn Thieving XP if their fruit are broken by your intact fingers. Smart naturalists could get Agility XP by growing Barberry bushes.
As for the second kind, get prepared to see many well-known sights. Take an example. At present, you can get snape grass and potato cacti by farming, which is approved the first time in Runescape.
Some new plants like swamp tar and swamp lizards, and butterfly flowers can also be found. By the way, reed beds make toads, and butterfly flowers introduce ruby harvests. Moreover, chances are you may get a chance to spawn a Guthixian butterfly if you are lucky enough. That is in fact great XP in your lowest-levelled skill when caught. This is not very relative to cheap Runescape Powerleveling .
There are also other quests you can have a try. If you have equipped yourself with sufficient Construction skill, you can grow grapevines by building some rack. When it is time for a harvest, you would get a lot of inviting grapes. What’s more, you can add water to it, and then wait for the fermentation. And wines are made in this way. If you like it, you can also mix the wine with other brew potions of their own gods. That’s how super Guthix rest potions, super Saradomin brews and super Zamorak brews are made.
