The perianth, which consists of floral leaves encircling the androecium and gynoecium, is a non-reproductive (accessory, sterile) component of the flower.
It is divided into two whorls: outer and inner whorls. The outer whorl of the perianth, the calyx (calyx), is largely made up of little green sepals (sepala), whereas the inner whorl, the corolla (corolla), is mostly made up of vividly coloured petals (petala).
Color, shape, and size of sepals and petals vary to a greater or lesser extent.
Final Answer:
The non-reproductive parts of flowers, known as perianth, are made up of the calyx and corolla, which together contain the reproductive parts.
