It's my first year growing Iron Cross oxalis deppei. I'm just southeast
of Chicago, about a mile or so from Lake Michigan.

My oxalis are still blooming, although the morning glories got killed
off by last weekend's cold weather. Will they survive in the ground or
should I dig them up? And if so, how should they be stored?

I think we're up to zone 6 now, 5 if the winter is cold.
