Detailed explanation-1: -Pansy. Pansies have a tolerance to low-temperatures and actually thrive in cool weather (40°-60°F) (Kwon 1992). They are capable of surviving temperatures down to the single digits, but when the air temperature drops below 25°F, pansy foliage will wilt and turn a gray-green color.
Detailed explanation-2: -Winter pansies bloom during the winter months in climates with relatively mild winter conditions. In areas where the winter season brings harsh weather, they bloom in early spring. Their tolerance of cool weather makes them a suitable choice for garden beds in USDA hardiness zones four to seven.
Detailed explanation-3: -Pansies prefer sites that provide full, direct morning sun, yet shield them from intense afternoon rays. Well-drained, fertile soil that’s high in organic matter helps fuel abundant pansy blooms.
