Native to Central and South American, Brassavola orchids are named after the Venetian nobleman and physician, Antonio Musa Brassavola. They have long, thin, tubular leaves that can reach up to a foot in length and sometimes appear unrolled or flattened. The tubular leaves are designed to reduce water loss, making them more drought tolerant than many other orchids. As a result, the plants need less humidity and less frequent water than many other epiphytic orchids.

Lady-of-the-night orchid is generally found in lowland tropical forests or mangrove swamps, growing on trees or on exposed rocks and cliffs near the shore. The white to pale green flowers are usually about 3½ inches in diameter and extremely fragrant in the evening. Each flower has long, slender sepals and petals and a large, heart-shaped lip on the tubular lower petal. The lip may have purple or dark red spotting inside the tube. B. nodosa is a very easy orchid to grow, adapting to a wide range of conditions in cultivation.

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, which means 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.
