Orchids also vary in color, appearing in shades of pink, green, dark purple, lavender, violet, blue, yellow, to white. Each petal is smooth, velvety, and soft with a crisp, succulent, and tender consistency. The flower of the orchid plant is colorful, fragrant and can vary in sizes from microscopic plants (Platystele) to long vines (Vanilla) to gigantic plants (Grammatophullum). There is an outer whorl of three similar segments called sepals. Within the sepals is another whorl of three segments called petals. Found all across the globe, orchids contain three petals, three sepals, one column, and a single protruding lip, called a labellum. Labellums are the part of the orchid where pollinating insects sit and utilize as a landing pad. One of the most telling characteristics of orchids is their unmistakable symmetry.
