Green Grass. Pearl’s Premium Ultra Low Maintenance Lawn Seed grows at a quarter the rate of blue grass and puts down 12-inch-deep roots that tap into naturally occurring moisture, says the maker. The resulting lawn requires no chemical fertilizer, little or no watering (after the first year), and mowing only once a month, the company claims. The seed comes in 5-, 25-, and 50-pound bags for $35, $170, and $300 respectively. Pearl’s Premium, 508/521-9940,
