I'm hoping someone can help me decide between the two.

We are seeding our yard which is very dry. I've read that Argentine is better-looking with less seed heads but may be harder to start from seed. Plus, the purity of the Pennington Argentine seed is only 46%. That makes me hesitant to go with Argentine. I don't want to waste money and time and not have the seeds germinate. But is Pensacola ever used as lawns? Would my lawn look like a pasture?

We just want a decent looking lawn that can survive the Florida heat with out costing us a fortune in water.
