umbel

Imagine a tiny umbrella made of flowers. That's the basic idea here. It is a type of flower cluster in which the stalks all spread out from one point, like the ribs of an umbrella. You often see it on plants such as carrot, parsley, dill, fennel, and Queen Anne's lace. The name comes from the Latin word umbella, meaning "little shade," a reference to its shape.

Botanists use this word when they want to describe that exact pattern of growth, and it often appears in gardening books and plant guides. If you are looking at wildflowers, this shape is a helpful clue for identifying certain plants.

An umbel is a specific type of inflorescence, which is the botanical term for the way flowers are arranged on a plant. In this arrangement, the flower stalks rise from the same point and spread outward, forming a shape that looks a bit like an open umbrella. Because the stalks begin together, the top often appears rounded or fairly flat.

This pattern is common in the carrot family, Apiaceae, and it is one of the features people use to recognize plants in that group. Good examples include dill, parsley, fennel, carrot, coriander, and Queen Anne's lace. In some plants, each main stalk carries a smaller cluster of the same shape, which is called a compound umbel.

The word is mainly botanical, and it is used in field guides, gardening writing, and plant descriptions when a precise term is needed. If you are walking through a garden or meadow and notice a flower head that spreads neatly from one center point, you are probably looking at this kind of cluster.
