Common to Secret
Those are the only two rarity names explicitly present in the official description. It says there are 10 tiers in total.
Rarities, huge plants and mutations.

A fully grown plant appears when a thrown seed lands. The developer advertises more than 75 plants and an in-game Index for collecting them. The official description is not a full plant catalogue. For the mechanics behind reaching more zones, read how to throw farther.
The game advertises 10 rarity tiers, from Common to Secret. The public description does not name the eight middle tiers or publish rarity probabilities.
Huge sizes and rare mutations are mentioned by the developer. Their triggers, visual markers and income effects remain unverified.
This site publishes a plant record only when its name and rarity have been observed in the game. The public developer description gives totals, not a complete catalogue.
Those are the only two rarity names explicitly present in the official description. It says there are 10 tiers in total.
The description mentions a very rare Secret and rare mutations, but it does not publish a complete probability table or mutation multiplier. Artwork text is not enough to establish a general rate.
The developer says “75+,” so the advertised count is at least 75, not a fixed list of exactly 75.
A promotional image can show an example result, but a complete list needs the in-game Index or repeatable direct observations. We do not infer unseen entries from a screenshot.
For each discovery, record the name and rarity exactly as the game displays them, along with the date you saw it. If the game shows a size or mutation label, record that separately rather than treating it as a rarity tier. This keeps an Index checklist useful even while the game changes.
The developer advertises 10 rarity tiers, but the public description only names the two ends of the range. A tier name is not a probability. Likewise, the phrase “rare mutations” does not tell us how often they happen or how they affect income. A complete public chart needs direct evidence from the game.
