Turned out great, most of it is 5-6' tall. I planted Cave in Rock switch which is known as a tall sturdy grass. The most important thing is controlling the competition. 1st make sure you prepare the area by killing all vegetation with Round-up. Do not till! The seed needs to be put in shallow, broadcasting over top works as well. The best way to control weeds and grass competition after seeding is with a heavy dose of atrazine. Atrazine is a restricted use spray and you will need someone with an applicators license to apply it, or at least purchase it. Not sure what works best in your area but in the Midwest it works best to frost seed in February.
