I've written about Frost Flowers before, but I don't remember ever seeing them this early.
This teakettle was formed from the stem of a White crownbeard flower (Verbesina virginica). Dr James Carter has the definitive page on Frost Flowers. He's also done a lot of fun experiments on extruding ice from pipes (also here).
The forecast was for 23°F last night (-5°C), but here in our glacial little microclimate, it was 13°F (-11°C) when we woke up this morning. Too bad it's not always 10° cooler in the summer too.
