Now that its cold out and my Russian can no longer naturally graze on my lawn I was wondering what are some easy to grow and quick growing plants that she can graze on? I have had limited success with wheat grass as she's not huge on it. I do also have prickly bear, Xmas cactus, a jade plant, and a few other edible house plants growing but they are far to slow growing to be fed off regularly. Any suggestions would be nice!
