Gardens in the context of "Shugakuin Imperial Villa"

Ornamental bulbous plants, often called ornamental bulbs or just bulbs in gardening and horticulture, are herbaceous perennials grown for ornamental purposes, which have underground or near ground storage organs. Botanists distinguish between true bulbs, corms, rhizomes, stem tubers and tuberous roots, any of which may be termed "bulbs" in horticulture. Bulb species usually lose their upper parts during adverse conditions such as summer drought and heat or winter cold. The bulb's storage organs contain moisture and nutrients that are used to survive these adverse conditions in a dormant state. When conditions become favourable the reserves sustain a new growth cycle. In addition, bulbs permit vegetative or asexual multiplication in these species. Ornamental bulbs are used in parks and gardens and as cut flowers.

The Katsura Imperial Villa or Katsura Detached Palace (桂離宮, Katsura Rikyū; Japanese pronunciation: [ka.tsɯ.ɾa ɾʲiꜜ.kʲɯː]) is an Imperial residence with associated gardens and outbuildings in the western suburbs of Kyoto, Japan. Located on the western bank of the Katsura River in Katsura, Nishikyō-ku, the Villa is 8km distant from the main Kyoto Imperial Palace. The villa and gardens are nationally recognized as an Important Cultural Property of Japan.

The grounds of the villa are regarded as a notable exemplar of traditional Japanese gardening. Tea ceremony houses within the strolling gardens and the main villa itself are all sited to maximize appreciation of varied foliage and changing seasonal vistas.
