Plants, mankind’s greatest enemy, are finally on the ropes thanks to global warming. Teach your children how to hunt the last of these enormous nitrogen junkies by observing them in captivity with today's Groupon. For $10, you get your choice of either one 4-inch phalaenopsis orchid or one 6-inch guzmania bromeliad at Tropical Designs (up to a $21.48 value).

For 35 years, Tropical Designs' green-thumbed design staff has created lush, colorful arrangements for homes, businesses, and special events. Fans of dainty décor can display the soft petals of a 4-inch phalaenopsis orchid in their living rooms, or opt for an exotic 6-inch bromeliad to lend color and angular pizzazz to the otherwise drab and curvy inside of an igloo. With a vibrant selection of sophisticated florals and colorful containers, Tropical Designs is able to bring the earth's ripest bounty from the outside in, creating tropical domestic paradises sans stifling humidity and monstrous human-mosquito hybrids.
