Lady’s slippers, a native North American orchid, grow east of the Mississippi River in moist woodland areas, open-forest swamp areas, fens, and along riverbanks. Plants are known for their pouchy flowerers that look like a little slipper. They can grow in gardens if the temperatures never climb above 90°F in the summer, there is dappled shade, and their soil is kept moist.
Cymbidium plants, also known as boat orchids, grow outdoors year-round in USDA hardiness zones 9 to 12. In colder climates they must be brought indoors during the freezing winter months. Plants produce a dozen or more flower spikes, with each one having a large 2 to 5-inch flower. To successfully grow plants – whether indoors or out – nighttime winter temperatures should be between 45°F and 55°F and plants need full sun.
