Best viewed at night, installation artist, Bruce Munro, has created a radiant and colorful installation at Longwood Gardens in Philadelphia open to the public. Using 20,000 Illuminated stems, numerous CDs made to resemble water lilies, and a large amount of LEDs along a hillside, the 23 acres of land is worth exploring. The Garden hosts a range of activities through the summer including music events, craft nights, and contests.
