While I certainly wouldn't be interested in the immobility, the idea of an eidolon with some real plant characteristics is certainly an interesting one. Maybe another two-step evolution like unnatural aura-undead appearance. The first one would give something like a stealth bonus in nature, the ability to regenerate hit points in sunlight, something like that. Then the second one would give bonuses against mind-affecting effects, paralysis, poison, etc. Something very similar to to undead appearance. Maybe some other unique and nature-y bonus.
