New England violet is strikingly beautiful, one of the so–called stemless blue violets, the largest subgroup of over 70 species of violets in eastern North America.

There were plenty of chores to be done this fall – finish picking the last of the apples, harvesting the carrots, beets, and other root crops, transplanting wildflowers into the meadow and beneath the big spruces, extracting the honey from the beehive, and getting the firewood in. But the skies were bright blue, the temperatures … Continue reading A Beaver Pond in the Autumn Glory of the North Woods
