Gardeners' Notes:

This lovely trillium grows in the woods on my property and they make a white carpet in early spring. They are very widespread here. The petals on mine do not have ruffled edges. They are small and low to the ground - just about 3-4 inches off the ground, and the flowers face upwards. They are so pretty and a welcome sign of spring.

The Snow Trillium is by far the earliest flowering trillium here and a wonderful showy plant. Absolutely hardy, as might be expected as it's heartland in the wild centers on Indiana, Illnois and Iowa where it frequently gets covered in snow whilst flowering and seems immune to being frozen solid. Here in SE Pennsylvania it flowers in early to mid-March, long before most trilliums are even through the ground. the flowers are pure white to creamy-white, of heavy texture and prominently veined, and replete with beautiful golden yellow anthers. Although it is typical of the pedicellate trilliums in that it's leaves are unmarked, they are unique in that the best forms have leaves which are a wonderful shade of blue-green, overlaid with a pewter caste, often with the veins picked out with silver speckles.
