Plum in Grow a Garden 2

The Plum can be obtained through the Harvest Pack with a 4% chance of obtaining.

Average sell value is 4,800 Leaves at 9.0 kg average weight, which makes it ranked 13 of 93 crops by sell value.

Prime window is 4m, and it is multi-harvest, so it keeps producing after the first pick.

Sell value scales with weight, so the honest efficiency measure is value per kilogram. The Plum returns about 533 Leaves per kg. That ranks it 21 of 83 crops for value density.

For reference, the most efficient crop in the game is the Atlantic Giant Pumpkin at roughly 40,000 per kg, and the median across all 83 crops is about 133.

Among Legendary crops, 1 sell for more than the Plum and 11 sell for less.

The higher-value Legendary options are Rocket Pop (22,500).

The game calculates a fruit's sale price like this:

Price = SellValue × SizeFactor × SizeMultiplier × MutationMultiplier × DecayPenalty × FriendsBonus, rounded down.

The part that matters most is SizeFactor, which is Size raised to the power of 2.5 for almost every crop. That is steeply non-linear: a fruit 50% larger sells for about 176% more, and one at double size sells for roughly 5.7×.

Two crops override it — Mushroom uses 1.9 and Bamboo 1.75, so oversized specimens of those are worth proportionally less than they would be otherwise.

Above a size of 5, diminishing returns kick in and the exponent drops to 1.5. Enormous fruit are still worth more, just not on the same curve.

Decay costs 80% of value at full decay, and each friend on your server adds 10%.
