Sandy soil, cool season grass, un irrigated, and low maintenence... seed with a fescue mix ( sheeps, blue and red fescues). these grasses are what you see durring the "Open Championship" across the pond. Fescues germinate in the 7-10 day range and thrive in dry sandy soils and can be maintained at cutting hieghts from 3/4 " to a no-mow turf stand.
Blue grasses will typically take at least 14 days to germinate, granted the seed stays moist for the entire 14 days.
Perrenial rye can be used if mixed with a seperate variety of seed in the northern climate ( fescues, Bluegrassess) but needs to be used more as a "nurse grass" because of its rapid germination but, it will eventually die off because of its lack of cold hardiness.
