Specializing in succulents and drought-tolerant plants, Living Green Nursery pumps oxygen into the atmosphere with its massive selection of retail and wholesale plants, many of which are grown on the shop's extensive grounds. A sprawling net reaches over verdant rows of potted plants and trees ($2.99+) and lush patches of vegetables and herbs ($2.99). Living Green Nursery's excellent selection of water-retaining succulents and other drought-tolerant vegetation helps achieve any hydrophobic gardener's wildest dreams ($1.99–$19.99). In addition to its extensive cache of plants, Living Green Nursery also offers several options for outdoor furniture ($199–$2,500), flower-complementing pottery ($8–$200), and fountains ($99–$300) for bathing avians or squirrels looking for a place to wade while drinking a gin and tonic. After selecting the flora of their choice, blossom boosters can head over to Living Green's planting station where the nursery's green-thumbed gurus can assist in the assembly of colorful customized containers of their new photosynthesis-dependent friend.
