Answer: Wish I had seen the commercial! According to University of Florida Extension Service, "St. Augustinegrass has the best tolerance for shade of any of the warm-season grass species and will also grow well in full sunlight. The most shade-tolerant cultivars are 'Seville', 'Delmar', 'Floraverde', and 'Captiva', all of which can sustain with 5-6 hours of sunlight. 'Floratam', which is the most widely used St. Augustinegrass cultivar, has relatively poor shade tolerance and requires six to eight hours of sunlight daily.
Zoysiagrass cultivars such as 'Empire' have moderate shade tolerance, somewhat similar to Floratam St. Augustinegrass
Centipedegrass will tolerate moderate shade. Bahiagrass, seashore paspalum, and bermudagrass are sun-loving species that will not do well in shaded conditions."
That's the only information my research turns up so I hope one of these turfgrasses is the one you saw in the commercial.
