Rhubarb

Rhubarb is a fruit crop that grows from Rhubarb Seeds after 13 days. It is a six-stage crop, with growth taking 2 days for each of the first three stages, 3 days for stage 4, and 4 days for stage 5 before it becomes ready to harvest. Once fully grown, it can be harvested like other standard crops.

Rhubarb is notable for being classified as a fruit crop in-game even though it is used in ways that align with other produce. It can be placed in the spool of the Sewing Machine to create the dyeable Green Buttoned Vest. It can also be used as a red dye source in the dye pots found in Haley's and Emily's house at 2 Willow Lane.

• Rhubarb Seeds are the source item needed to grow it.
• Total growth time is 13 days.
• Its crop cycle consists of stages lasting 2, 2, 2, 3, and 4 days before harvest.
• It has a dye use, making it useful beyond shipping or cooking-related purposes.
• It can be used in tailoring to make the Green Buttoned Vest.

In real life, rhubarb is considered a vegetable because the edible part of the plant is the stalk, but in Stardew Valley it is treated as a fruit crop.
