One day a cackling little elf offers you a gift. He can give you a seed from ANY plant; from worlds you thought were only fictional. With only some soil, and whatever care the plant needs, it will grow into the full adult version! Magic or tech far beyond your world's understanding could be brought to your backyard. All you have to do is ask for a plant. He will only give you one seed, so choose wisely.


Rules:

Any plant in fiction is game.

If you ask for a sentient plant creature, like a Disgaea demon, Treefolk, or Plant Pokemon; the seed will sprout into a baby version. It may or may not have a personality similar to any of the canon versions. It will be a sentient creature for you to raise.

While most plants only need some dirt, exceptionally large trees like Yggdrasill or the World Tree from DBZ MIGHT have some negative consequences on your surrounding property. The Elf won't tell you about that and won't help you with any problems you get into about that, so think carefully.
