November 22 and I have not had a frost yet (a microclimate thing, there have been some light frosts within blocks of my place.)   But no hard frosts anywhere in the near region. Roses are still blooming, and petunias where they are situated just right. Statisically speaking, our average first frost date is still October 15, but it as been a few years since we have had a killing frost by then.

Noticing, in the absence of frost, the effects of what I figure must be day length on a number of plants.
