Guaiacum
Guaiacum sanctum
Holywood lignum vitae (Guaiacum sanctum) is a critically endangered tropical tree renowned for its exceptionally hard, resinous wood and vivid blue-purple flowers. It prefers full sun to partial shade, well-drained alkaline soil, and warm, frost-free conditions typical of Caribbean and Central American climates. This rare conservation-worthy specimen is best suited to tropical or subtropical gardens and requires patience, as it is extremely slow-growing.
