The Lakeside daisy (Tetraneuris herbacea) is a beautiful spring-blooming plant found only in a few Midwestern states and Ontario, Canada. Because of its rarity, it is a federal threatened and state endangered species. The heart of its U.S. range is on the Marblehead Peninsula, Ohio, where botanist Clarence M. Weed named it in 1890 after discovering it growing near Lakeside. Thousands of Lakeside daisies occur in the active Lafarge Quarry in Marblehead, but the population is declining because of limestone mining operations. In early May, it blooms in a spectacular display of bright yellow flowers, while during the rest of the year only rosettes of leaves are visible. The Lakeside daisy thrives on barren limestone gravel and pavement known as alvar and survives in this habitat only where there is little competition.
