About Lignum vitae
Guaiacum officinale, known as Lignum Vitae or Tree-of-Life, is a slow-growing, long-lived tree renowned for its exceptionally dense wood and medicinal resin. It features dark green pinnate leaves and distinctive blue-violet flowers that bloom intermittently, adding an exotic splash of color. Ideal for dry tropical gardens or as an ornamental specimen in areas with well-drained soil, where its compact form and striking bloom can be admired.
Native range
Caribbean, including the Greater and Lesser Antilles, and the northern coast of South America
Care tips
It thrives in full sun for optimal flowering and healthy growth, tolerating drought well once established. Watering should be moderate, allowing the substrate to dry out completely between waterings, as it is susceptible to waterlogging. It prefers sandy or rocky soils with excellent drainage and a neutral to alkaline pH. A common mistake is overwatering, which can lead to root rot in this species adapted to arid conditions.
