Pansies are a low growing early flower. They have a good blooming season if they are in a cool place and are not permitted to dry out from the hot sun. They can be planted as early in April as the ground will allow. The plants will flower well into June and later if the dead flower heads are picked off. Sometimes pansies will reseed themselves.
Pansy seeds can be dug into the ground in late August to winter over, or started in window gardens in early spring. However, the Needham Historical Society will be offering plants that can be planted immediately.
