Guaiacum
Guaiacum officinale
Guaiacum is an exceptionally slow-growing tropical tree prized for its dense hardwood, beautiful violet-blue flowers, and long history of medicinal use. It requires a warm, frost-free environment with full sun to partial shade and well-drained soil. Patience is essential — this tree grows only a few inches per year but rewards the dedicated gardener with long-lived ornamental beauty.
