A Festive Appearance
From a distance, Guayacan (pronounced "why-a-con") (Guaiacum angustifolium) appears as if it might be an evergreen in the Cupressaceae (Cypress) Family such as a Juniper or Cedar. Upon closer inspection, it becomes evident this shrub has pinnately* compound leaves with thick, leathery, dark green, small leaflets. Guayacan is in the Zygophyllaceae (Creosote-Bush) Family.
In late Fall and persisting into Winter, there are bright, scarlet-red seeds, giving the shrub a festive appearance:
I have heard numerous stories in the South Texas oral tradition about the Guayacan being used as a Christmas tree during the Great Depression of the 1930s by families that could not afford to purchase a traditional Christmas tree. The root bark makes an excellent soap for washing woolen products, so another common name for the shrub is Soapbush.
