Wildflowers of 2014 - #19 Large-flowered Trillium (Trillium grandiflorum)
This plant is a species that I have been watching for a week, waiting for blooms to open. The weather was finally warm enough and the sun was out from the clouds long enough for a few Large-flowered Trillium (Trillium grandiflorum) blooms to open. When the blooms on this flower are completely open, they are the largest flowers of any Spring-flowering plants in Mid-Michigan. Some Trillium flowers may be up to 5.5 inches across.
Like many of the other species that I have photographed this year, these flowers are currently blooming in the rear part of Chipp-A-Waters Park in Mt. Pleasant.
To learn more about the Large-flowered Trillium, look at this species profile I posted in 2013.

Wildflowers of 2014 - #20 Blue Cohosh (Caulophyllum thalictroides)
The second wildflower of the day was Blue Cohosh (Caulophyllum thalictroides). This is another Spring ephemeral - it completes its yearly cycle of flowering and growth before the overhead trees leaf out. While the Large-flowered Trillium has very large noticeable flowers, the pale green flowers of the Blue Cohosh are small and inconspicuous. Despite the small size of the flowers, this plant is visited by a variety of pollinators including bumblebees. After pollination, the plant produces small dark-blue berries that often remain on plant stalks throughout Summer, Fall, and Winter.

The third flower of the day is a close relative of the Dutchman's Breeches (Dicentra cucullaria) that I photographed on April 21st. Squirrel Corn (Dicentra canadensis) has the same fern-like leaves as Dutchman's Breeches - in different shade of green. Like Dutchman's Breeches, it also has white flowers that hang from a stalk, but instead of looking like pairs of pants hanging by their ankles, the flowers of Squirrel Corn look more like hearts.

So why is the plant called Squirrel Corn? If you dig up the roots of the plant you will find these small pale-yellow bulblets (tubers) that resemble kernels of corn. Squirrels, chipmunks, and mice will often dig up this plant to consume the bulblets.
|Squirrel Corn is named after these yellow root nodules|
