Green thumbs mean many things, including the fact that someone is an avid gardener, 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 $40 worth of plants at Scioto Gardens in Delaware.

Scioto Gardens' green-thumbed cultivators care for a selection of food-producing foliage and aesthetically pleasing yard adornments. Scioto's nonsentient pet offerings include winterberry holly ($34), a deep-green plant with bright red berries, and the Rozanne geranium ($12), capable of blooming for upward of four months. With wide frond spreads, wood ferns ($12) project simplistic displays of color, and Jerusalem Artichokes ($16) unfurl chocolate-scented flowers, shading the soil under which edible, potato-like tubers grow. Fall presents an ideal planting time for growers of all experience levels, as regular rains and lower temperatures help plants to establish robust root systems before the ground freezes.

Owners Michael and Linda Johnson channel their joint passion for horticulture into Scioto Gardens and since the shop's founding in 1999 have purveyed an assortment of native and exotic plants grown to steadily survive in the Ohio area. Michael and Linda bring up each plant in a special blend of compost and local soil packed with nutrients that aid in the development of each frond, petal, and incongruous femur.
