Cabbage is not related to lettuce, nor is spinach. Raddiccio and kale are related to cabbage, as are broccoli, cauliflower, mustard greens and a couple others. Spinach is elated to neither lettuce nor cabbage.

So you should be good with most other greens that are not lettuce.

For my part, the whole cabbage family is evil and bad (I miss broccoli) but lettuce and spinach are still okay!
