About
Trillium nivale, commonly known as Snow Trillium, is one the first flowers to emerge. It can be very difficult to spot because of it’s size and it often blooms when there is still a light blanket of snow on the ground. It is a very rare flower with only a few sizeable populations around Ohio.
The single flower grows from a rhizome and typically only reaches a couple inches tall. It has three leaves arranged radially around the stem, a flower with three petals, yellow pistils, and three sepals. The plant can take 12 years to flower, so it usually has many juveniles around it. There are many species of Trillium in Ohio, but Snow Trillium is by far the most petite and delicate.
Bloom Window
The bloom period in Ohio is very short lasting only about a week, with each flower only lasting a few days. Like most spring wildflowers, the bloom time depends on the weather and the zone, but it’s usually toward the end of winter, and often when there is still snow on the ground.

Where to Find It
Hardwood woodlands across midwest US, but in Ohio, the southeast corner of the state seems to be more suitable where the bedrock is sandstone. However, I have seen some on the limestone outcroppings in the southwest part of the state as well. I have found sizeable populations in Clifton Gorge State Nature Preserve, Chalet Nivale Nature Preserve, and Miller Nature Sanctuary State Nature Preserve.
