Your thread title says "winter peas AND cereal rye" and then you jumped in with "are THEY worth mixing with rye and crimson clover?" It made it sound like you wanted to mix both winter peas AND cereal rye with rye AND crimson clover. Thus my question. Some guys get confused about rye, winter rye, cereal rye, annual ryegrass, etc. Took me about 5 minutes to realize it was just a case of bad editing and ambiguity.
