Depending on the region where they are planted, pansies can last from early spring until the heat of the summer arrives. In the fall, they will last until temperatures reach as low as 1 degree F, and they can even survive a blanket of snow.
Pansies come in a summer and fall flowering annual in the north, and a winter and spring blooming biennial in the south and southwestern U.S. They have a wide range of colours, including single and multicoloured flowers.
Pansies are perennials with five vertical petals that are hardy with a long flowering period.
Pansies grow to be 8 to 9 inches tall, and they should be planted about six to eight inches apart.
Pansies can be used as bedding plants, and they also do well in containers, and window or patio boxes. Regularly deadhead (pluck off the dead blossoms) pansies to ensure their continued flowering. Pansies thrive in cool weather in partial shade.
The flowers and leaves are edible, and contain vitamins A and C. Pansy flowers can be used to make dye.
