Mary Helen Wingate Lloyd

She married financier Horatio Gates Lloyd, Sr. (1867-1937), and redesigned the gardens on their estate, Allgates, in Haverford, Pennsylvania.

The main house at Allgates was designed by Philadelphia architect Wilson Eyre, and the estate is now on the National Register of Historic Places.

The centerpiece of Lloyd's landscaping was a bowl-shaped iris garden roughly 100 feet in diameter, consisting of four concentric terraces descending to a sunken grassy area with a tiled pool in the middle.

[1] Lloyd amassed a small but substantial horticultural library, which was given to the University of South Carolina in 1982 after her son Richard's death.

[3] The library also holds a hand-colored lantern slide of the iris bowl garden from the 1920s or early 1930s.
