Walnut Grove Nursery
The rich soil of Walnut Grove Farm—tilled throughout more than 150 years and four generations—sprouts with flowers, shrubs, and trees sold in an eponymous onsite nursery. Arched greenhouses plant their pillars in the grounds' northwest corner, where they shelter shrubs such as boxwoods and holly, annuals such as petunias, mums, and pansies, and more than 80 fragrant perennials. Mulches chipped from hardwoods and cypress join peat moss and compost to blanket exposed roots, and a Gardener's General Store stocks country essentials ranging from grass seed to locally laid eggs. Walnut Grove's green-thumbed experts also emerge beyond the nursery walls to beautify lawns with landscape designs and routine maintenance such as edging, weed control, and flamingo herding.
