Catalpa speciosa, also known as the northern catalpa or cigar tree, is a deciduous tree native to the central United States. It can reach a height of up to 70 feet (21 meters) with a spread of up to 50 feet (15 meters). The bark is gray-brown in color and becomes furrowed with age.
The leaves of the Catalpa speciosa are large, heart-shaped, and can grow up to 12 inches (30 cm) long. They are arranged in an alternate pattern along the branches. The tree produces fragrant, white, trumpet-shaped flowers in late spring or early summer, which attract bees and other pollinators.
The Catalpa speciosa is often planted as an ornamental tree for its unique appearance and shade-providing capabilities. Its wood is also used for various purposes, including fence posts, railroad ties, and furniture.
The tree is hardy and can tolerate a wide range of growing conditions, including drought and poor soil quality. However, it may be susceptible to certain pests and diseases, such as the catalpa sphinx moth and verticillium wilt.
Catalpa speciosa has also been used in traditional medicine to treat various ailments, such as asthma, bronchitis, and fever. However, its medicinal properties have not been extensively studied, and it is not recommended for use without consulting a healthcare professional.
