🌿 Coriander
A cool-weather herb that bolts almost immediately in heat — a summer sowing mostly yields seed.
🌱 This one is in the reference and the planting calendar, but you cannot sow it in the game yet.
Coriander at a glance
Is Coriander frost tolerant?
Yes, through light frosts. Damage starts at -4°C and it is killed below -8°C.
What temperature does Coriander grow best in?
It grows best between 8 and 24°C. Below 4°C it stops growing altogether, and above 26°C it slows down.
How many days does Coriander take to mature?
About 40–55 days. That is a typical figure: it needs roughly 520 °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 Coriander a cool-season or warm-season crop?
A cool-season crop. It does best in the mild weather of spring and autumn, and slows down in summer heat above 26°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 Coriander is ready when that total reaches 520. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.

| Degree days to maturity | 520 °C·dThe heat budget it must accumulate before it is ready to pick. |
| Comfortable range | 8–24°CWhere it grows without stress. |
| Frost damage below | -4°CLeaves start taking frost damage below this low. |
| Killed below | -8°CBelow this it does not come back. |

| Yield per bed | 5 bunches |
Things worth knowing
- Heat and long days send coriander straight to flower, so a summer sowing is really a seed crop.
- Between 10 and 20% of people taste soap in coriander, which traces to a variant in a single smell-receptor gene.
