The best time for wildflowers is when the maples are in bloom before the leaf canopy shades the forest floor.
Red trilliums are the showy ones. They occur throughout the park.
White trilliums can be found east of Wilno and then not until the west side of Algonquin. They really like hardwood bush!
I found a few examples of "white" red trilliums around km 17 in the Park. I assume it is a rare genetic defect.
Striped Trilliums bloom on Centennial Ridges trail and also on the portage into PInetree Lake.
Red trilliums often bloom together with yellow Trout Lilies.
They can bloom in shade, but prefer sunny spots.
Trout Lilies like sun!
Small spring beauties also bloom at this time of the year.
Later when the tree canopy starts to leaf out, wild cherry and apple blooms appear.
Spring truly is the season of "50 shades of Green".
The melt water streams are still keeping the forest floor wet.
The cooling shade of the new forest canpoy permit fungi like the Ghost Plant to thrive.
This one was fruiting beside the Spruce Bog trail boardwalk.
Later in the summer, Meadow Sweet bushes light up the forest.
and Cardinal Flowers bloom amid the rocky, scoured areas at the edge of flowing waters.
