Holywood -Guaiacum sanctum

With showy blue flowers that are evident year round, holywood is a slow growing Holywood Guaiacum sanctumevergreen tree. Small yellow heart shaped berries follow the flowers but are also often present at the same time as flowers. With a rounded canopy that is often compared to a Crape-Myrtle, holy wood can be grown as a small, multiple-stemmed tree.
