Peach Leaf Curl is a springtime disease caused by the fungus Taphrina deformans.  The fungus can infect peach (Prunus persica) as well as a few other plants in the Prunus genus.  The disease can be devastating in fruit orchards, but it can also appear on ornamental (flowering) peach trees in landscapes and nurseries; the "ornamental" designation does not impart resistance.
