Can I put my happy little shamrock outside? Oxalis regnellii. Per Western Garden Book, it is a houseplant. Per the tag, it is hardy to 20 degrees. Per info on web, it is hardy to Zone 7 (I forget what site I found this on). I'm Zone 8. I assume it will do fine during the summer, and will just have to see what happens over winter. I'm horrible with houseplants. Also wondering why the tag says do not consume while other information has it as edible (a type of sorrel).
