About Mountain immortelle
Erythrina poeppigiana, commonly known as Mountain Immortelle, is a fast-growing deciduous tree native to tropical American regions. It is renowned for its spectacular red-orange blossoms that appear on bare branches before the leaves, creating a vibrant contrast in landscapes and agroforestry systems. It is ideal for shade, windbreaks, and as an ornamental tree in large gardens or estates.
Native range
Tropical Central and South America, from southern Mexico to northern South America (including the Caribbean).
Care tips
It requires full sun for optimal flowering and prefers well-drained, fertile, and slightly acidic to neutral soils. Watering should be regular during establishment, reducing once the tree is mature, as it tolerates dry periods. Avoid waterlogging, as it can lead to root rot. A common mistake is planting it in confined spaces, as its large size demands ample room for full development.
