Kilei zera'im: Ethiopian khat, mustard and kale
Question
Among the vegetables I grow in my backyard raised bed garden is Ethiopian kale. I understand it is botanically related to both the kale and mustard families.
In my experience, it is very similar to regular kale in both appearance and taste and does not have a pronounced mustard flavor.
May I plant Ethiopian kale close to other kale varieties or is there a concern of kilayim and a required separation between them?
Answer
Dr. Mordechai Shomron, agronomist
Standard kale and Ethiopian kale are similar and are not considered kilei zera'im, so they can be planted near one another. Although Ethiopian kale is botanically related to mustard, it is considered kilei zera'im with mustard.
