crop Savoy cabbage,
where this is mentioned in the description.
Savoy cabbage seeds are capable of germinating at soil temperatures from +3 °C. Young plants at the cotyledon stage are resistant to frosts down to -4 °C, and hardened seedlings can withstand temperature drops down to -6 °C.
Mature plants of late-maturing varieties demonstrate high frost resistance, enduring autumn frosts down to -12 °C. Exposure to moderate sub-zero temperatures during this period has a positive effect on the taste quality of the heads, allowing for extended harvest periods compared to other types of cabbage.
