The ground is filled with more than semicursed treasure chests and fully candied dinosaur bones. Let nature's soil-sitters watch over your subterranean cache with today's Groupon: for $20, you get $40 worth of plants and garden accessories at Reseda Nursery & Stone Yard in Madison.

Reseda Nursery & Stone Yard gratifies green thumbs and greenhorns alike with its expansive collection of garden ground fillers, from flowers and mulch to decorative stone. After incubating in local greenhouses from a motley assortment of seed varieties and cuttings, an apple-cheeked legion of annuals, perennials, veggies, herbs, trees, and shrubs reside in Reseda's massive nursery, lying in wait for a watering can to call Pop-Pop. Assorted plant bedding starts at $11.99, and gloomy gardens can benefit from a cradle of Encore azaleas ($24.99), which scrub scowling storm clouds in a chromatic bath of rainbow-colored radiance.

Come the auburns of autumn, the addition of a maple tree ($89.99) in the backyard begets a lifelong legacy that drops enough brilliantly hued leaves to conveniently bury your doctor-rejected and chicken-neglected deep fryer for years to come. Along with a staff of experienced horticulturists and garden gurus, Reseda also boasts an impressive selection of lawn and garden supplies to assist in flora fostering and fertilizer funneling.
