Tabebuia rosea, commonly called pink trumpet, rosy trumpet tree or pink poui, is an evergreen (usually considered deciduous in climates with a dry season) tree with a long, smooth trunk topped by a rounded spreading crown. It typically matures in the wild to 60-90' tall and to 30-50' wide, but usually grows shorter in cultivation. It is native from Mexico through Central America to Venezuela and Ecuador. It is best noted for its often spectacular bloom of showy, trumpet-shaped, purplish-pink to white flowers (2-4" long) with yellow throats which bloom in clusters (up to 30 flowers per cluster) at various times during the year. Bloom schedule in part depends upon the climate where the tree grows. In climates with a distinct dry season (e.g., March - May), the leaves of this tree will typically drop at the beginning of that dry season. The dry conditions subsequently trigger a mass bloom near the end of the dry season when the tree branches are still bare but the rains have begun to fall. In climates where rains occur throughout the year (no dry season), flowers tend to bloom intermittently through much of the year in smaller but more frequent bursts of bloom. Flowers are followed by bean-like pods (8-12" long). Each palmate leaf has five, leathery, scaly, elliptic to elliptic-oblong, toothless, medium to dark green leaflets (central one to 12" long) with undulate margins. Rosy trumpet tree is the National Tree of El Salvador. It is an important timber tree in Mexico and Central America. Winter hardy to USDA Zones 9-11 where it is best grown in deep, fertile, moist, well-drained soils in full sun.
- Prepare a mixture of half potting soil and half sand, perlite or vermiculite. Put the mixture in a pot with drainage holes in the base.
- Water the mixture so that it is moist but not wet.
- Put the seeds on the soil.
- Cover the seeds with a thin layer of soil.
- Water the seeds.
- Place the pots in an area with warm temperatures in full sun or part shade.
- Water them regularly so that the soil does not dry out.
- When the seedlings are a few inches tall, they can be transplanted.
