Frost flowers on white crownbeard

On frosty mornings I’ve continued to enjoy frost flowers on our dittany (Cunila origanoides) and I recently saw them for the first time on white crownbeard (Verbesina virginica), also known as frostweed. I planted it last spring because it’s another host for frost flowers. Even so, I was taken by surprise at its first display of ice crystals.

First frost flowers of 2012

I was delighted to discover my first frost flowers of the season on dittany plants (Cunila origanoides) on November 13, 14, and 15. Our nighttime temperatures were in the mid 20s and were the lowest we’ve had this fall. I was thrilled to find these ice sculptures in our backyard for the first time last year (Frost flowers and Frost flowers #2). Seeing them again this year suggests that their occurrence is somewhat predictable.

Three Tough Plants

It’s been cold this last week – daytime highs below freezing, nighttime lows in the teens, and we’ve had a little snow. However, a few of the backyard plants seem to take the cold in stride. This Christmas Fern (Polystichum acrostichoides) is still quite green.
