⚪ Turnip
An ancient European staple that grows fast and round in cool weather.
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) − 5), and Turnip is ready when that total reaches 480. That is why the same seed takes a very different number of days in Dublin and in Guangzhou.
| Base temperature | 5°CBelow this, the plant accumulates no growing degree days at all. |
|---|---|
| Degree days to maturity | 480 °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 | -5°CLeaves start taking frost damage below this low. |
| Killed below | -10°CBelow this it does not come back. |
| Heat stress above | 27°CAbove this the plant slows down and stops setting fruit well. |
| Typical time to harvest | 40–55 days |
| Yield per bed | 9 turnips |
Things worth knowing
- Before the potato arrived, turnips helped feed Europe through winter.
- The first jack-o'-lanterns were carved from turnips — Irish immigrants switched to pumpkins in America.
