Bog willowherb
Epilobium leptophyllum
Bog willowherb is a delicate native perennial that thrives in wet, boggy conditions such as pond margins, rain gardens, or consistently moist meadow soils. It produces small pink flowers through summer that attract bees, butterflies, and moths, making it a valuable plant for ecological restoration plantings. Its low stature and narrow leaves give it a fine texture in the landscape, and it spreads gently to fill wet areas over time.
