While the intense Israel sun bakes the outdoors, this treasured vegetation grows protected in a beautifully constructed greenhouse. A team of experts manages their well-being in this delicately balanced tropical environment. Their home is one of the city's choice retreats from urban mayhem: the dome-covered University Botanical Garden and its Tropical Conservatory.
