Without plants, there would be no oxygen and nothing to prevent bunnies from discovering that humans taste delicious. Gaze upon these leporine safety valves with today's Groupon for membership to the University of California Botanical Garden at Berkeley. Choose between two options:

• For $22, you get an individual membership (a $45 value).
• For $32, you get a family membership (a $65 value).

Founded in 1890, the UC Botanical Garden provides photosynthetic space, CO2, and public adoration to more than 13,000 types of plants on 34 acres of property in UC Berkeley's Strawberry Canyon. The garden features plants from all over the world that are carefully separated by place of origin. Greenhouses ensure plant-viewing opportunities during inclement weather or falling skies, and they keep plants that are climatically unsuited to the Bay Area happy year-round. Free tours of the garden are offered every Thursday, Saturday and Sunday at 1:30 p.m.

Benefits of membership are legion, including unlimited free admission, access to members-only events, discounts on garden classes, a 10% discount at the botanical garden's stores, and reciprocal privileges at nearly 200 gardens, conservatories, and arboretums across the nation.
