Green thumbs mean many things, including the fact that someone is an avid gardener, a semisuccessful finger painter, or actually just a gecko in need of a lift to the next truck stop. Add some color to your opposable digits with today's Groupon: for $20, you get $45 worth of perennials, shrubs, trees, grasses, and evergreens at Blossom Nurseries in Yorktown Heights.

Brady Cullen harnesses his degree in horticulture and landscape design from Cornell University to cultivate greenery with advanced, environmentally friendly approaches that yield lush blossoms, stronger specimens, and healthier flora. Blossom Nurseries blooms more than 10,000 perennials on-site ($12.99 for large varieties), as well as grasses ($24.99), evergreens ($19.99+), and sweater-clad lawn gnomes, all of which thrive when planted during the temperate weather of September. Petal peddlers also use their green thumbs to sprout lawn-sprucing shrubs ($29.99+) and primp 10-inch hanging baskets to adorn barren porches ($18.99). If overwhelmed by the sheer volume of bumblebee bait, gardeners can seek the counsel of the plant emporium’s on-site landscaper, who is available to help customers to determine which plants best suit the idiosyncrasies of their yards or to offer advice on what to do when posies begin singing show tunes and demanding human flesh.
