The plaza at New York City’s famed Flatiron Building will be flanked through Aug. 2 by “Solar Flowers” up to 18 feet high.

The oversized sculptures are partially powered by solar panels on their petals and stems.

Each flower can seat up to 10 people, who can access free Wi-Fi service and charge cell phones and laptops. Charging stations will be available 8 a.m. to 9 p.m. daily.

The flowers are part of Toyota’s 2010 Prius advertising campaign, whose theme is “harmony between man, nature and machine.”

After their New York run, the flowers will travel to Chicago, Seattle, San Francisco and Los Angeles.
