This 20,000-square-foot greenhouse stocks more than 1,200 different annuals and perennials, including hundred-plus varieties of hostas, 75 ornamental grasses and more than 100 day lilies. Specialty items, such as Japanese maples ($1,200) and jumbo-size minty green echeverias (two-gallon pot, $22), are sent home with care sheets to reduce possible “black thumb” casualties. A well-stocked tropical department seduces with the heavenly scent of orchids (from $30). In addition to tools, seeds, home decor and fertilizers, you’ll find such staples as pea gravel ($6 per 18-kilogram bag), flagstone and rockery stone (25 cents per pound), plus bulk triple-mix and mulches.
