Pink trumpet tree (Tabebuia heterophylla) is a species of flowering tree that is native to the Caribbean Islands. It is commonly cultivated as both an ornamental tree and for its use in the timber industry; the wood is relatively strong for its weight and is widely used to build furniture and boats.
I. Appearance and Characteristics
Tabebuia heterophylla is a species of tree native to the Caribbean, and is also cultivated. It is also known as Roble blanco, pink manjack, pink trumpet tree, white cedar, and whitewood.
Tabebuia heterophylla grows up to 20 to 30 feet tall. Leaves are opposite and palmately compound with five or fewer leaflets. T. heterophylla is considered brevi decidius. Flowers are Showy pink, tubular and five lobed (2 to 3 inches long). The flowering time is spring and Summer. Fruit is a seedpod, it splits along 2 lines to shed the numerous thin light brown seeds (1/2 to 1 inch long with 2 white wings).
The flowers of Tabebuia heterophylla are in an inflorescence of the umbellate type. It is a perfect and complete flower with radial (actinomorphic) symmetry, and the whorls of the corrolla and the calyx are connately joined. The ovary is superior with an axile placentation, two locules and two carpels.
Pink trumpet tree contains alkaloids that pose mild toxicity to humans, cats, and dogs through contact or ingestion. Symptoms in humans include skin irritation, nausea, vomiting, and diarrhea. Cats and dogs may also exhibit gastrointestinal upset. Immediate veterinary care is essential if pets are poisoned. Handle pink trumpet tree with care, particularly around children and pets.
II. How to Grow and Care
Temperature
Pink trumpet tree shows remarkable resilience to temperature variations, enduring cold temperatures down to 0°C (32°F) and heat up to 43°C (110°F). While hardy, it may need protection during extreme cold to prevent frost damage. Signs of cold stress include leaf discoloration and drooping. In excessive heat, wilting and scorched leaf edges are common symptoms. To mitigate these effects, provide temporary shelters, adequate watering, and mulching. Its broad temperature tolerance makes pink trumpet tree suitable for diverse climates, though care should be adjusted to prevent stress in extreme temperatures.
Watering
Pink trumpet tree thrives in environments that mimic its native tropical settings, where it is accustomed to periods of heavy rain followed by dry spells. This species exhibits a preference for moderate humidity and has adapted to tolerate short droughts. Watering should be spaced out to once every three weeks, allowing the soil to dry slightly between sessions. As an ornamental tree often grown outdoors, pink trumpet tree demonstrates resilience in various climate zones, but adequate water during its growing season ensures optimal flowering and growth.
Fertilizing
To promote pink trumpet tree’s lush growth and vibrant blooms, apply a balanced fertilizer every 3 months during the growing season. A slow-release formula is ideal, providing steady nutrients and enhancing flowering potential. Use sparingly; over-fertilization can harm. Adjust feeding with seasonal growth changes—less in winter. For safety, follow instructions on quantity and water well post-application to prevent root burn.
Pruning
Known for its stunning pink blooms, pink trumpet tree benefits from pruning in early spring before new growth starts. Remove dead, damaged, or crossing branches to improve air circulation and shape the canopy. Regular maintenance encourages healthier flowering and prevents disease. Always use clean, sharp tools to avoid infections. Prune lightly to maintain the tree’s natural form and ensure long-lasting beauty.
Propagation
Pink trumpet tree thrives best when propagated through cuttings. To optimize success, use semi-hardwood segments and ensure cuttings have a node, as this is where root initiation is most likely. Keep the substrate moist and warm to encourage rooting, which is crucial for the establishment of pink trumpet tree. Proper care during the early stages can lead to strong and vibrant growth, allowing gardeners to enjoy the ornamental beauty of pink trumpet tree’s pink blooms.
Transplanting
For pink trumpet tree, the prime transplanting period is during the late spring to early summer months, when the mild temperatures support root establishment. Choose a sunny location with well-draining soil to encourage healthy growth. Keep the root ball moist and handle with care to minimize stress on the plant.
III. Uses and Benefits
This tree is valuable for its timber production and grown for such purposes on plantations. It is commonly harvested from the wild for use locally and for export.Pink manjack is used as a street tree. Its height allows for it to provide lasting shade and as a result it can provide shade for a residential property near the patio or deck. Its floral display allow it to be valued and as a result, it is known as an ornamental tree.
