I garden in Dutchess county, close to New Hamburg. Last fall I left my woodland garden in Westchester, NY, and it’s been an adventure watching plants emerge here this spring. This mystery plant is growing in a seasonal wetland that borders the back of my 6 acres. The area is wooded with a stream that appears to flood from early spring, then slowly recedes to its regular banks by fall. I’ve been watching these 3-4 ft tall plants, expecting to see yellow iris or cattails, but instead nodding bell-shaped white flowers in twos/threes that resemble very tall snowdrops. I vaguely remember seeing drawings of similar plants in bulb catalogues that I have not yet unpacked (will I ever finish!) Any thoughts?
