🌿 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.
Parsley at a glance
Is Parsley frost tolerant?
Yes — it is one of the hardier crops. It shrugs off frost down to -6°C and is only killed below -12°C.
What temperature does Parsley grow best in?
It grows best between 7 and 25°C. Below 4°C it stops growing altogether, and above 28°C it slows down.
How many days does Parsley take to mature?
About 70–90 days. That is a typical figure: it needs roughly 880 °C·d of warmth above 4°C, so a warm season gets it there sooner and a cool one later. The city calendars below give the sow and harvest dates for each place.
Is Parsley a cool-season or warm-season crop?
A cool-season crop. It does best in the mild weather of spring and autumn (and through winter where winters are mild), and slows down in summer heat above 28°C.
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.
