Tabebuia rosea aka Pink Poui

Tabebuia rosea is a tropical tree in the Bignoniaceae family. Common names include pink trumpet tree, pink poui and roble. Its native range runs from Mexico through Central America. It also reaches Colombia, Venezuela and Ecuador. It grows in moist forests and some drier woods. It also occurs in open fields and along roads. Useful Tropical Plants reports its conservation status as Least Concern.

The tree forms a rounded crown with wide-spreading branches. Wild trees reach 60–90 feet [18–27 metres] in height. Their crowns span 30–50 feet [9–15 metres]. Some accounts give a maximum height of 98 feet [30 metres]. Garden trees tend to stay smaller, but sources give no clear range. The long, straight trunk may form buttresses at its base. Its bark can be grey or brown. Each compound leaf has five leaflets. The tree can keep its leaves in some climates. Where a dry season occurs, it often sheds them.

The tree can bloom while its branches lack leaves. Its trumpet-shaped flowers range from purple-pink to white, with yellow throats. Each flower measures 2–4 inches long. Clusters may hold as many as 30 flowers. Bloom times vary with the local climate. The sources describe seasonal flowering rather than a fixed month range. PFAF reports that flowering can start three years after planting. Long, narrow capsules follow the flowers and add visual interest. These fruits are not edible.

Grow this tree in full sun and fertile soil. Deep soil that stays moist but drains well suits it best. Useful Tropical Plants says it grows in most fertile soils. Missouri Botanical Garden lists USDA hardiness zones 9–11. It rates water needs as medium and maintenance as low. Growers can raise plants from seed, cuttings or air layers. The tree provides shade for lawns, streets, coffee and cocoa crops. People also harvest its wood for furniture and other timber uses.

Missouri Botanical Garden reports no major pest or disease problems. Leaf spot and dieback can occur, and spider mites need watching. PFAF records no known food uses or hazards. That does not establish safety for people or pets. It lists traditional remedies made from bark, flowers, leaves and roots. These reports do not prove that the remedies work. Useful Tropical Plants also flags weed potential without stating its severity.
