Orchids have a unique flower structure, which this Phalaenopsis orchid shows off.

They’re bilaterally symmetrical, the left and right halves being mirror images. The column in the center of the flower is a fusion of the male and female parts. They have three petals in an inner whorl and three sepals, usually as big as the petals, in an outer whorl.

The lower petal is the lip on which pollinators land. When the flower is in the budding stage, this lip starts out at the top. In most orchids, as the flower opens, it rotates until the lip is at the bottom, a process called resupination. Not all orchids do this. Some remain in the original upside down position and some rotate a full circle until they’re back where they started.
