Acorns of Floramorphosis

These odd looking acorns were created by the elven arch-Druid Celendreil. Celendriel, a hermit who despised outsiders interfering with her nature meditation. After one particularly annoying evening Celendriel sat down and created buckets of these magical acorns (all she had to bind the spell to). Now instead of answering questions she'd simply throw an acorn and the person would be instantly turned into a beautiful, green tree. This solved both of her problems at once: no outsiders, but no killing them either and it gave her a nice new tree. Training the local squirrel population to use the acorns, the Forest of Forgotten Souls quickly garnered its name and has been avoided since.

The acorns can only be used once, but throwing them activates their magic so that the next person that touches them turns into a tree (as per Plant Form Other) except it requires a Remove Curse or Plant Form Other spell to be cast to reverse.
