Lily of the valley

Jacob's ladders (Lilies of the valley in ) are a type of flower in the, that first appears in. They spawn only when the town is in perfect condition. This flower does not have any variations, appearing only as a cluster of whitish-green buds dangling from a leafy plant. This plant does not breed when placed next to other Jacob's Ladders. They typically spawn at the top of cliffs (one per acre), except in, where cliffs do not appear.

Further information
The real-life Jacob's ladder is known as a "Polemonium" and has mostly purple or blue flowers and appears very different from the one that appears in the game. The in-game Jacob's ladder is based off a lily of the valley.
