Sure thing. If you like "cold hardy", also consider Tatsoi and 'Tyfon'.
'Tyfon' = Holland Greens OP 20-40 days first cutting, 60 DTM
Cut-&-come-again every 35 day. Very productive.
Cross between stubble turnips & Chinese cabbage.
Forage, cover crop, salad, greens.
Very hardy: to 10 F,
Tender when young, very mild flavor. No "mustard" flavor.
