Gardenia is a plant that belongs to the rubiaceae family. It takes its name from a Scottish botanical Garden, which lived in the 18th century. This plant fears frost and is often grown indoors, although it is of course possible to plant it outdoors to decorate your garden with its green and shiny leaves and white flowers.
