Green thumbs mean many things, including the fact that someone is an avid gardener, semi-successful finger painter, or actually just a gecko in need of a lift to the next truck stop. Add some colour to your opposable digits with today's Groupon: for $20, you get $40 worth of plants and garden supplies at Tumino's Garden Centre.

Tilling and planting since 1964, Tumino's Garden stocks a varied lineup of gardening, landscaping, and soil supplies. Let soilsmiths lend a knowledgeable helping hand when picking out an array of garden tools ($3.99+), or put a handheld shovel to work by bringing home colourful perennials ($2.99+) from Tumino's vast selection of perpetual petal machines. Dirt lover's dreams span both indoor and outdoor display areas, so after passing through the gravel detectors and emptying pockets of spare stones, blossom boosters can shop for horticultural accents in climate-controlled comfort all year round. Yard decor includes statuary ($25+) and a Versailles-worthy lineup of shrubs and evergreens ($16.99+), and with Tumino's family-run penchant for custom-made outdoor arrangements, shrubs can be used to decoratively mark property lines for encroaching neighbours and claim-jumping gold-hunters.
