Arboretums are the art museums of the plant world, packed with breathtaking colors and hidden orchid messages targeting an elite group of floral intelligentsia bent on world control. Star in your own botanical thriller with today's Groupon: for $22, you get a one-year membership to Jenkins Arboretum & Gardens in Devon (a $45 value).

With 46 acres of gardens and 1.2 miles of paved, flower-lined walkways, Jenkins Arboretum is a verdant, tranquil haven hidden in the heart of a bustling commercial and residential area. The area is home to an array of native trees, shrubs, and wildflowers. Many rare and endangered species are available for viewing, such as monkshood, box huckleberry, and the Pennsylvania money tree, which protects its naturally occurring coinage by tickling tourists. Self-guided walking tours and periodic educational displays and workshops educate foliage fanciers about the many species in the arboretum—and speak to the importance of preserving native flora. Members receive free and discounted admission to special programs, and they receive voting privileges, newsletters, and a "thank you plant" grown from Jenkins Arboretum's botanical collections.

Reviews

Three Yelpers give Jenkins Arboretum & Gardens a four-star average:

• Just wander through the few themed walks (Azalea Hill is particularly pretty) and enjoy the nature that surrounds you. – Aron G.
• Nice, well-maintained, extensive public garden. No frills -- just paved paths through greenery…My two-year-old son loved it. It's definitely manageable with kids. – Nathan R.
