🌿 Parsley
A biennial: leaves in year one, then it overwinters and runs to flower and seed in year two.
🌱 This one is in the reference and the planting calendar, but you cannot sow it in the game yet.
What the numbers mean
These are the actual parameters this game runs on. Growth is driven by growing degree days: each day contributes max(0, min(mean temp, 28) − 4), and Parsley is ready when that total reaches 880. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.
| Base temperature | 4°CBelow this, the plant accumulates no growing degree days at all. |
|---|---|
| Degree days to maturity | 880 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 7–25°CWhere it grows without stress. |
| Frost damage below | -6°CLeaves start taking frost damage below this low. |
| Killed below | -12°CBelow this it does not come back. |
| Heat stress above | 28°CAbove this the plant slows down and stops setting fruit well. |
| Typical time to harvest | 70–90 days |
| Yield per bed | 8 bunches |
Things worth knowing
- Parsley is biennial — leaves the first year, flowers the second, which is why an overwintered plant suddenly bolts in spring.
- The seed is famously slow, often two to three weeks; soaking overnight speeds it up considerably.
