After a gorgeous fall or spring day comes a chilly night and - you guessed it - light frost damage. These morning glories had an eastern exposure and got nipped by Jack Frost. Both the vein clearing and the dark, water-soaked blotches are symptomatic of frost damage.
Low areas and areas with wind exposure are often the first to get damaged by frost. To extend the life of your tender annual flower and vegetable plants, cover them with a sheet or use insulating row covers.
