Cypripedium parviflorum

The yellow lady's-slipper, a hardy terrestrial orchid found across much of Canada and the United States in woods, fens and meadows. It is a garden or cold-frame plant, not a houseplant: it needs a real winter dormancy near freezing and a cool, moist, airy root run in summer.

Mesic upland woods with deep leaf litter, shaded bogs and fens, mountain meadows and canyon seeps, on subacid to neutral or limy soils.

Measured sites run from 55 to about 1,300 m; western mountain populations reach roughly 1,800 to 2,900 m.
