Run by the famous Royal Horticultural Society, the RHS Garden Wisley is the society's premier garden. Located in southeast England in Surrey, the garden's signature icon is its new greenhouse -- the Glasshouse. Created for the Royal Horticultural Society's bicentenary, it was even officially opened by Her Majesty Queen Elizabeth [source: Royal Horticultural Society].
The Glasshouse resides on a peninsula in the middle of a lake surrounded by outdoor plantings. The actual 40-foot (12-meter) structure houses three different climate areas [source: Mahr]. The tropical zone includes a large waterfall feature and a pond filled with water lilies. The moist, temperate zone boasts tree ferns and palms, while in the dry, temperate zone, you can find cacti and succulents [source: Royal Horticultural Society].
