While out raking leaves this weekend I noticed viable (for now) terminal buds on fig trees, several inches of sprouted florence fennel, whiteflies still present on kale, and a grasshopper. It is surprising what surives our up and down weather.

Prominent buds on overwintering branches can be typical for a range of tree/shrub species. The fennel might not have gone completely dormant yet, which is also normal. Whiteflies and many other insects can often withstand chilly temperatures before a deep freeze (which we haven't had yet) either kill them or render them inactive. Overwintering insects protect themselves from freezing by creating compounds in their blood that act like antifreeze.
