Handroanthus impetiginosus seed
LATIN NAME: Handroanthus impetiginosus
COMMON NAME: Pink Ipê, Pink Trumpet Tree, Lapacho
The pink ipê is one of the most spectacular flowering trees in the world, and it earns that reputation honestly. It is a tall, deciduous tree that can reach fifteen metres or more, with a broad, open crown of compound leaves. But the real show comes in late winter and early spring, when the leaves fall and the bare branches erupt in clouds of trumpet-shaped flowers in shades of pink and lavender. A single tree in full bloom is unforgettable, and in its native South America, whole streets and hillsides turn pink for weeks. The flowers are followed by long, hanging seed pods that split open to release flat, papery, winged seeds that drift on the breeze.
The pink ipê belongs to the trumpet-vine family, Bignoniaceae, and it is native from Mexico through Central America to Brazil and Argentina, where it grows in dry forests and open country. It is a tough tree, tolerating heat, drought and poor soil, and it is admired not only for its flowers but for its extraordinarily hard, durable timber.
Positive & Encouraging Seed Germination Guide
Growing pink ipê from seed is easier than most people expect, and the results are dramatic. The flat, papery seeds are short-lived, so sow them fresh. They need no treatment, just warmth and moisture. In late winter or spring, press the seeds onto the surface of a pot of free-draining seed compost, cover them very lightly, and keep them warm and evenly moist. Seedlings appear quickly, often within one to three weeks, and they grow fast in warm conditions. Pot them on as they grow and protect them from frost while they are young, since the tree is tropical. Given sunshine, warmth and a little patience, a seed can become a flowering tree in a handful of years, and the first time you see those pink blooms on a tree you raised yourself, you will understand why this is one of the most loved trees in the tropics.
Scientific Research & Plant Biotechnology
The pink ipê is a serious subject in both medicine and forestry. The inner bark, known as lapacho or pau d’arco, contains naphthoquinone compounds such as lapachol, which have been studied for decades for their antimicrobial and anti-inflammatory activity, and the tree remains an important plant in South American herbal medicine. In forest science, the ipê is prized for its timber, one of the hardest and most durable woods in the world, and sustainable cultivation and reforestation programs have been developed to grow it while protecting wild stands. Its spectacular flowering also makes it a focus of urban-tree research, as cities in the tropics and subtropics plant it for its beauty and hardiness. From the laboratory to the city street, the pink ipê has a wide and growing record of study.
Ecological & Economic Value & Wide Applications
Ecologically, the pink ipê is a treasure. Its mass flowering provides an enormous nectar source for bees, hummingbirds and other pollinators early in the season, and the tree gives food and shelter to birds and wildlife. It is a cornerstone of many tropical gardens and streetscapes.
Its economic value is substantial. The timber is among the most valuable hardwoods in the world, used for decking, furniture, flooring and heavy construction, and sustainable plantations now supply much of this demand. The bark is harvested for herbal medicine, and the tree is grown widely as an ornamental, with a strong market in tropical and subtropical landscaping. For a grower with warm conditions and patience, the pink ipê is a tree that pays back in beauty, shade and timber for generations.
