Tecoma is a genus of flowering plants in the family Bignoniaceae. The genus includes various species of shrubs and small trees that are native to the tropical and subtropical regions of the Americas, particularly South America.

One well-known species of Tecoma is Tecoma stans, commonly known as yellow bells or esperanza. It is a popular ornamental plant cultivated for its vibrant yellow trumpet-shaped flowers. Tecoma stans is native to the southwestern United States, Mexico, and parts of South America.

These plants are known for their attractive flowers, which often bloom in clusters and can be yellow, orange, or red in color, depending on the species. They typically have a tubular shape with flared lobes at the end. Tecoma plants are also characterized by their pinnately compound leaves, which are composed of multiple leaflets.

In addition to their ornamental value, some Tecoma species are used in traditional medicine for various purposes. For example, Tecoma curialis, native to the Amazon rainforest, is used in indigenous medicine for treating various ailments.

It's worth noting that while Tecoma plants can be visually appealing and have certain medicinal uses, they are not edible and should not be consumed. As with any plant, it's important to exercise caution and ensure you have accurate knowledge before using it for any purpose.
