Argentine bahia grass develops a darker green color with slightly denser lawn coverage. The leaf blades are short and wide. By contrast, Pensacola bahia grass produces longer, narrower leaf blades and develops significantly more seed heads if not mowed.
Both Argentine and Pensacola grass selections tolerate cool, lightly frosty winters and dry soils, but Pensacola demonstrates exceptional drought tolerance with its extensive root system that penetrates 7 to 10 feet deep. Both also tolerate summer heat well.
Argentine bahia grass grows best in climates that are hot and humid and with infertile soils that remain on the moist side. Pensacola bahia is the better choice in regions with cooler and drier conditions.
