Here in the city of Pittsburgh we dodged the frost bullet on Tuesday morning. The temperature fell to 28o but the air was so dry that no frost formed.
Our flowering trees were untouched and by yesterday morning the petals were falling and the seed balls on the London plane trees were on the verge of disintegrating (shown above).
As I walked to work a gust of wind sent the petals and seeds into the air. The petals fell fast and drifted into the gutters but the plane tree (“sycamore”) seeds on their tiny parachutes floated like snowflakes. It was beautiful … and impossible to photograph.
On a warm sunny morning we had sycamore snow.
