Mandrake

Mandrake applies a respectable x8 sell multiplier, and its tell is subtle: the fruit emits small purple particles rather than recoloring dramatically, so you need to watch your crops closely to confirm the mutation actually rolled before harvesting. That x8 sits comfortably in the strong mid-tier, well above basic green or growth mutations but below the triple-digit storm payouts.

The important context is that Mandrake is tied to a pet and tagged Limited, which shapes how you obtain and use it. Rather than waiting on weather, this is a mutation you enable through owning and deploying the corresponding Mandrake pet, giving you far more agency over when the purple-particle effect appears on your beds. The Limited tag, however, means the pet is not always available, so securing it during its window is the real gatekeeper.

Is it worth it? For a player who can acquire the pet, yes, an x8 you can influence on demand is reliably profitable and stacks multiplicatively with rarity and weather mutations for compounding sales. The honest caveat is the Limited availability: if you miss the pet, you miss the mutation, so prioritize it while it is obtainable.
