Two in one suggestion:

Would be really nice to have Mandrake harvestable. As it is at the moment, the only way to obtain them is via a chest or killing mobs in Lake Halard with that low drop chance.

Second suggestion: Herbs become farmable. Herbs seeds and so on, allowing players to farm and sell them to others.

All herbs and alchemical plants get seeds.

Shy snow flowers don't, mandrake don't, etc.
Its mostly eggregious when it comes to making ear patches in my opinion, since the large mushroom potions are rarely used.
