| Kossak F1 (treated) |
 |
Slightly flattened globe, pale green |
Medium maturity, large-framed kohlrabi with a unique feature: It can be harvested at 65 days. It looks like most other varieties, but when left in the field, it just keeps growing. Even at the giant size, it maintains crisp texture and is crunchy and sweet. It does not get woody. Stands in the field well into late fall and has an excellent shelf life. |
