Without trees to generate oxygen, humans would have to retrieve it from scuba tanks and the minty breath of local supermen. Keep the air alive with today's Groupon: for $15, you get $30 worth of plants at Buena Creek Gardens in San Marcos.
The serene 4-acre Buena Creek Gardens fills local gardens with more than 5,000 varieties of flowering plants and showcases botanical innovations in demonstration gardens. An octogenarian pepper tree shades visitors as they stroll through the entryway, leading them to shelves replete with flourishing leaves and gardens that demonstrate the art of attracting avian life, beneficial insect life, and the migrating flocks of biographies from recently closed bookstores. One-gallon Sweet Kate plants ($7.95) and Poorman's rhododendron shrubs ($8.95) adorn yards and gardens with collars of delicate jewel-toned blooms. Lush trays of spiky echeveria succulents ($5.95–$19.95) sport verdant crimson-tinged leaves alongside steadfast resistance to drought and stoic perseverance when suffering through gardeners' dated comedy routines. Sinuous Medusa Head succulents ($15.95) pepper landscapes with sprawling tentacles and mesmerizing floral centers, and garden sculpters can summon armies of lepidopterae and beneficial insects with a vigorous 5-gallon Golden Purple butterfly bush ($24.95). Florid peafowl strut through the grounds and flash their feathery frondescence, attempting to grab the attention of the swarms of butterflies and hummingbirds flitting through the air.
