Coca leaves, containing small amounts of cocaine, have been chewed as a stimulant for thousands of years in the Andes. Cassava crops provide a substantial source of carbohydrates in the tropics. Bruguiera, Rhizophora and other mangroves are planted to protect coasts from storms and to anchor beach sand. A single rootstock that supports a grove of quaking aspen may be the world's oldest living individual plant, at around 80,000 years. Hybrids of the wild pansy (Viola tricolor) and other species of the violet family are grown as ornamentals, even in temperate winters.
