Cenizo, also known as Texas Sage or Purple Sage, is one of the most beloved native shrubs of South Texas — famous for its silvery-gray foliage and the sudden appearance of vivid purple-pink flowers following rainfall. This behavior earned it the nickname 'Barometer Bush' because locals use it to predict rain.

When humidity rises before a storm, Cenizo responds within hours by bursting into bloom. A hillside of blooming Cenizo after a summer rain is one of the most spectacular sights in South Texas.
