Because plants have long been jealous of our ability to live indoors, they attempt to infiltrate our finest mansions and universities by slowly climbing stony facades. Visit a place built specifically to contain these floral strivers with today's Groupon: for $11, you get two adult admissions (a $22 value) to the Franklin Park Conservatory, located downtown on Broad Street. Today's Groupon cannot be redeemed on Thursday evenings.

A lush, diverse ecosystem of colorful plants and eye-opening exhibits await patrons to the Franklin Park Conservatory. Unveil the mystery behind carnivorous greenery at the interactive Savage Gardens display (through November 14), where visitors can observe a feeding of a Venus flytrap (1 p.m. daily), learn about how carnivorous plants digest horsefly gizzards, or grill a cactus on the latest fruit bat gossip. Feel free to stroll the museum's signature collection of original Dale Chihuly glass art, which decorates 12 gorgeous installments, or watch as in-house professional glass blowers use small puffs of air and careful craftsmanship to create twinkling vessels and life-size Burton Gilliam sculptures.

The conservatory's 88 acres of urban oasis expand from various biomes into surrounding gardens. Watch as chameleonic trees trade green for winsome autumnal hues, or simply file through the campus and botanical gardens to build your mental horticultural capital thanks to displays of herbs, culinary plants, native and perennial species, a buzzing apiary, and community gardens.

Reviews

TripAdvisors give the Franklin Park Conservatory an average of four owl eyes, and Yelpers give it an average of 4.5 stars:

• Overall, I feel this conservatory has a greater mix of exhibits than many others so it is appealing to a broader spectrum. Oh, and it's also nice and toasty warm on the inside to keep the tropical plants warm enough, so it's a great winter attraction! – eightwednesday, TripAdvisor
• My favorite part were the butterflies, which were everywhere...so many colors and sizes...really cool. – Ken G., Yelp
