Rarity is driven by a plant's Special Effect trait, which also gates access to reserved pots and the rare Alien Fantasy plant type. It is never based on a single cosmetic trait alone.
544 plants. No special effect — the standard range of plants, pots, and backgrounds.
172 plants. Carries the Sparkle effect — faint drifting motes around the canopy.
42 plants. Glow effect — and the only tier that can unlock the Alien Fantasy plant type.
10 plants. Golden effect — leaves and stem turn to gold, and the Gold pot becomes available.
9 plants. Rainbow or Crystal effect — the rarest possible pairing, with reserved fruit and the Crystal pot.
