calla

 

It was quite a surprise to me that the calla lilies survived this past winter, with -5F in the courtyard (the rhizomes are not supposed to survive freezing, which is more than 30 degrees warmer).  They also have grown despite my digging and destroying the emerging shoots (I had expected them to have frozen to death, so was preparing the soil for new plants). They seem to be none the worse for the wear however, and the first flowers just opened. My neighbor reports that her calla lilies did fine also.
