Chinese ground orchid is a terrestrial orchid that grows from flat pseudobulbs that resemble corms. Each pseudobulb produces 3 to 5 linear, sword-shaped, pale green leaves. Small, pinkish-purple flowers develop in racemes from March through June on long thin stalks growing 12 to 18 inches tall. Although it is advertised to be hardy to USDA Zone 5, it is best to mulch the plant to protect it and keep it warm in winter. Grow in part-shade areas in borders, rock gardens, or containers.

The orchid family consists of a large number of genera, each with its own unique characteristics. A common characteristic, however, is the basic form of the flower, which consists of three petals surrounded by three sepals -- often in dramatic and contrasting colors and in a variety of shapes and sizes. Although some orchids are native to temperate zones, most orchids tend to prefer a semi-tropical or tropical environment (USDA Zones 9-11) and have epiphytic roots -- meaning they derive moisture and nutrients from the air and support from another plant; few orchids grow in soil. Orchids usually prefer a diurnal temperature fluctuation -- meaning warmer days and cooler nights -- though the absolute temperature range (cool, intermediate or warm) varies by genus and is consistent with their natural habitat. While requiring adequate sunlight for a stunning bloom display, most orchids will not tolerate sustained direct sun.

Many varieties have pseudobulbs, a portion of the stem between leaf nodes that stores water to help sustain the plant through dry periods. Other varieties are monopodial, meaning upward growth is from a single growing point.

There is an exception to almost every general statement one can make about orchids. The family continues to challenge taxonomists.
