Pomegranate

The Pomegranate is a limited Rare crop from the Trader Event, which puts it in an interesting middle tier of the economy. Rare sits well above common shop fodder but below the Mythical and Prismatic heavy hitters, so its unmutated sell value is respectable rather than spectacular. The "limited" tag is what does the real work — once the Trader Event rotation passes, you cannot freely re-buy the seed, so scarcity slowly props up its value.

Its strength is an unusually wide type list: Berry, Flower, Fall, Leafy, Sweet, Summer, Sour, Fruit and Tropical. With nine tags it overlaps with a huge range of type-targeted boosters and seasonal items, meaning it catches mutation and bonus effects far more often than a single-tag Rare. That makes it a much better mutation host than its rarity alone suggests.

For progression, the Pomegranate fits the early-to-mid game perfectly: cheaper to obtain than top-tier crops yet able to scale into real money once you layer Gold, Rainbow or weather mutations on it. Sell plain copies for steady income, but hold and mutate the cleaner ones for a larger payoff.
