Evolution of the Species (3.5e Feat)
From D&D Wiki
Evolution of the Species [Epic, Jigyousho]
Since becoming a plant creature, you have learned to harness your ability to strengthen plants to such a degree that you can apply it to yourself.
Benefit: At the cost of 20 HD for your animate plants ability, you can grant yourself the Strength and Constitution bonuses given to your animated plants. Any extra hit points you gain from this ability only last as long as you maintain the 20 HD cost, and you take that amount of damage when you stop using the ability.
