Above: False Forget-Me-Not in the Thoreau Rain Garden in Madison, Wisconsin on May 16, 2022.
False Forget-Me-Not - Brunnera macrophylla
Siberian bugloss is valued as groundcover in shady areas, and has clumps of large heart-shaped leaves of about six inches. The plant has sprays of small blue flowers, similar to those seen in the related forget-me-nots.
Even though this is not a wildflower in Wisconsin, I'm including this plant only because the flower looks so much like the flower of the True Forget-Me-Not
and is a good reference to avoid confusion.
False Forget-Me-Not are native to the Caucasus, and are used in gardens. The plants I photographed were used in a rain garden and the flower is also planted in the Allen Centennial Garden's New American Garden in the University of Wisconsin-Madison.
Blooms April to May.
