Trillium grandiflorum grows wild around here and usually blooms in early April. The plants are around a foot tall and each bulb produced a stalk with 3 leaves and 1 white, unscented flower. As the flowers age, they change from white to pink. Other varieties have red or yellow flowers or patterned leaves, but this one is our local trillium. Besides enjoying it in the woods, there are quite a few of them spread around the garden.
The common name is Wake Robin, but I've never heard anyone call them anything but Trilliums. They are monocots and members of the Lily Family. It is native to the eastern half of the U.S. and Canada, as far south as Georgia and to the northernmost parts of Canada. These are woodland flowers and will be happiest in those conditions. A few of ours get some sun, but spend most of their days in the shade.
