Tulip magnolia trees bloom in Washington, on Feb. 28, 2017. Crocuses, cherry trees, and magnolia trees were blooming several weeks early because of an unusually warm February. The National Park Service predicted on March 8 that the peak bloom of the famed cherry trees at D.C.’s Tidal Basin would occur on March 14-17. This would put it on par with the earliest bloom on record: March 15, 1990. Photo: Cliff Owen, AP
