Bulbs are actually the modified stems of perennial monocotyledons*.
These plants have evolved to store food reserves in a globe-shaped underground bud that is protected with overlapping, expanded leaf bases. Some bulb plants, such as onion and garlic, have a papery protective layer over these underground leaves, while scaly bulbs, such as the lily, have no protective layer. Bulbs can be as tiny as a pea or as heavy as 15 pounds!

*The only exception is a few varieties of Oxalis, which are dicotyledons.
