Q.Will Oxalis Plum Crazy Wood Sorrel Survive Winter
I live in the eastern part of Pierce County (98374 zip code) in the State of Washington and would like to know if Oxalis Plum Crazy Sorrel will survive in our winters. The temperature often drops to 30 degrees and sometimes as low as 20 degrees Fahrenheit.

It is hardy to about 20 degrees F so I would mulch it well before winter. If you see weather predicted to be cooler, be sure and go out and cover your oxalis.
