White Mulberry

There's no honest farming math to run on the White Mulberry yet, because it's an unobtainable, unreleased Legendary crop: it exists in the game files but has no shop entry, no seed cost and no published sell price. Any economics around it are projection, not strategy, so the responsible take is to treat it as a preview rather than something to plan a garden around.

What we can reason about is its rarity tier. A Legendary classification sits in the upper-mid band of Grow a Garden's value ladder, comfortably above the Common and Uncommon staples but below the Mythical, Divine and Transcendent heavy hitters. If it follows the pattern of other berry-type crops, expect a modest base weight offset by multi-harvest potential, which would make mutation stacking, not raw size, the path to real Sheckles.

Until it actually releases, the practical advice is simple: don't chase it, don't trust any "exclusive method" claims to obtain it, and keep your currency liquid. The moment a verified seed cost and sell price land, this crop can be re-evaluated properly, with Wet, Gold and Rainbow stacks being the obvious first mutations to test on a Legendary berry.
