I planted some spinach seeds by the front step in late summer, forgot to water them and forgot all about them. One plant came up and have been slowly producing a few leaves. It has been doing fine, until these last few days. We are getting lows in the teens now. We have had a lot of very lovely 50 degree days. It was 32 for the high today. Growing season is over. If I had some sort of cover, I could keep it going a while longer.
