I definitely did a double take when I saw this tree (above) a few blocks from my house. Good news/timing from the National Park Service this morning:
“Stay calm, this is completely normal. This type of cherry tree (Prunus subhirtella var. autumnalis) regularly displays pink blossoms during warm periods in the fall & winter months. They’ll bloom again in the spring. See them on the Washington Monument grounds.”
