The ground is filled with more than semi-cursed treasure chests and fully candied dinosaur bones. Let nature's soil sitters watch over your subterranean cache with today's Groupon: for $12, you get $25 worth of flowers, plants, supplies, and more at Rainbow Gardens, with locations on Bandera Road and Thousand Oaks Drive.

Rainbow Gardens specializes in native plants and water-shunning xeriscape plants, which thrive in the Texas heat and provide a more eco-friendly lawn by requiring less irrigation. The stunning garden shop offers a huge selection of annuals, perennials, and blue mooneries, as well as everything a gardener needs to create a vibrant plant-filled habitat despite poor soil conditions. Each nursery has a minimum of five acres of inventory-packed space teeming with autotrophic life forms. The stock rotates regularly according to planting times, with headliners such as cacti, succulents, roses, and geraniums making vibrant and lauded appearances. Spruce up your path to the mailbox with a front yard bespeckled by four-inch annuals ($1.49+), four-inch perennials ($2.49–$2.99), and gallon perennials (starting at $4.98 and generally costing $6.99). Three-gallon shrubs for landscaping ($16.99) and five-gallon trees for indoor tree farming ($26.99–$34.99) are also available. The addition of houseplants or hanging baskets of flowers does more than just transform the aesthetic setting of a room—some scientists argue that plants can improve health. From the standoffish paeonia to the enthusiastic, misunderstood barrel cactus, there’s a plant to match everyone's personality. Use your Groupon to bring some healthy color and green energy to your space, or give someone special a gift of renewal and life.
