Orchid seeds are so small and light that a single pod can hold thousands of them.

The longer version

An orchid seed is little more than a thin coat around a few cells, with almost no stored food inside. That lightness lets one pod hold an enormous number, and the dust-like grains drift on air currents much farther than heavier seeds could travel.

The trade-off is that a germinating orchid cannot rely on reserves. Most species depend on a fungus in the soil to supply sugars and minerals until the seedling can feed itself. This partnership explains why orchids are often slow to establish and why many stay uncommon in natural habitats. A few species have seeds large enough to carry a visible food store, but they are the exception.
