Mt. Cuba, Hockessin, Delaware is a reserve of flora native to the Piedmont which stretches from New York state to Kentucky: a legacy of the Lammot du Pont Copelands.

Varieties of trillium.
Mt. Cuba holds a national collection: all 26 known native varieties with two or three exceptions which cannot be grown here.
