Steve Young at the NY Natural Heritage Program would like to know if you have seen nodding trillium lately. There is some discussion among NY botanists that it is becoming more rare in New York and may be in trouble. If you know of any populations of this trillium with nodding white flowers let Steve know at young@nynhp.org. Historically it was known from many spots from Long Island, up the Hudson Valley and west to the Niagara Region, primarily along the limestone belts. See the map from the cards at the State Museum below.
