Taxonomic Information

Appearance

Tecoma plants have a wide range of forms and sizes, but they generally produce dense foliage and showy flowers. The leaves are pinnate or bipinnate and are arranged in an opposite or alternate pattern. The flowers are trumpet-shaped and have five lobes, with the lower lobe being the largest. They are usually orange or yellow in color, but some species produce flowers that are red or pink. The fruit of Tecoma plants is a long, narrow capsule that contains numerous seeds.

Care Guide

Tecoma plants are relatively easy to care for and can thrive in a variety of conditions. Here are some tips for caring for these plants:

Water: Tecoma plants require regular watering during the growing season, but they can tolerate some drought. It is important to avoid overwatering, as this can cause root rot.

Fertilization: Tecoma plants benefit from regular fertilization during the growing season. A balanced fertilizer that contains equal amounts of nitrogen, phosphorus, and potassium is recommended.

Soil: Tecoma plants prefer well-drained soil that is rich in organic matter. They can tolerate a range of soil types, but they do best in soil that is slightly acidic.

Sunlight: Tecoma plants require full sun to bloom properly. They can tolerate some shade, but they will not produce as many flowers.

Hardiness Zones: Tecoma plants are hardy in USDA zones 8 through 11. In colder climates, they can be grown as annuals or in containers that can be moved indoors during the winter.

Common Pests & Diseases

Tecoma plants are generally resistant to pests and diseases, but they can be affected by a few common problems. Here are some of the most common pests and diseases that affect Tecoma plants:

Aphids: These small, pear-shaped insects feed on the sap of Tecoma plants and can cause stunted growth and distorted leaves. They can be controlled with insecticidal soap or neem oil.

Spider Mites: These tiny pests can cause yellowing leaves and a fine webbing on the plant. They can be controlled with insecticidal soap or neem oil.

Root Rot: Overwatering can cause the roots of Tecoma plants to rot, which can lead to wilting and death. It is important to avoid overwatering and to ensure that the soil is well-drained.

Habitat

Tecoma plants are native to tropical and subtropical regions of the Americas, including Mexico, Central America, and South America. They are often found in forests, on rocky slopes, and along riverbanks. Some species of Tecoma have been introduced to other parts of the world, including Asia and Australia, where they are often grown as ornamental plants.
