‘Nadia’ Eggplant Variety: Not So Good with Heat

Leading up to 2012, we had tried lots of different eggplants for yield and flavor, finally settling on Nadia as our favorite. The summer of 2012 was hot, and we discovered ‘Nadia’ eggplant has trouble setting fruit in hot weather. How hot are we talking about? We’re in central Virginia, winter plant hardiness Zone 7a, and AHS heat Zone 7.

You can access state heat zone maps and a key to the zones here. There are 12 zones on the map, indicating the average number of days each year that each region has “heat days” – those with temperatures over 86 degrees Fahrenheit (30C). That is the temperature at which plants start to suffer physiological damage from the heat.
