Prerequisites: Knowledge (nature) 24 ranks, wild shape 4/day.
Benefit: The character can use his or her normal wild shape ability to take the form of a plant. The size limitation is the same as the character’s limitation on animal size.
Source: Standard Reference Document under Open Game License v1.0a, which updated this feat originally published in the Epic Level Handbook, page 65. It is unclear how this feat differs from the plant creature wild shape ability that all druids get at 12th level. Perhaps it allows the druid to take the form of regular plants, not just plant creatures. One would think that the 2nd-level spell, tree shape, would be a less expensive solution suitable for most situations than an epic level feat slot. Perhaps an epic level druid named Rose always wanted to be one…?
