The Basics of Orchid Biology

Before we dive into orchid care, it's essential to understand the unique biology of these plants. Orchids belong to the family Orchidaceae, which includes terrestrial, epiphytic, and lithophytic species. Terrestrial orchids grow in soil, while epiphytic orchids thrive on other plants, such as trees, without harming them. Lithophytic orchids grow on rocks and stones.

Orchids have evolved to adapt to their environments, developing specialized roots, leaves, and flowers. Their roots are designed to absorb moisture and nutrients, while their leaves are often thick and waxy to conserve water. Orchid flowers are renowned for their intricate shapes, colors, and fragrances, which play a crucial role in attracting pollinators.
