I’m not sure. Mother used to grow them years ago. She passed a few years ago so I can’t ask her. I just remember I liked them steamed then put in a cream sauce.
The things I am planting are things I either do not see in the store, or they are too dang expensive in the store.
Kohlrabi is great steamed plus I like to just eat it out of hand in the garden. I just planted 72 starts of it this afternoon, now we need to find a way to preserve it. We planted 96 hills of potatoes yesterday... Red Gold, Yukon Gold and a new one called Purple Haze. Another week and I pull the Chinese Early Red Garlic and the little Vietnam garlic...
You haven’t grown them before?
Please let me know how you make out with them. I might try it. Zone 5A.
My Mother would bring a plate of veggies to us about an hour before supper. Sliced radishes, sliced kohlrabi, celery, etc., with a touch of salt on the side. Mmmm.
