Native to China and Japan, hostas are extremely resilient perennials that survive in heavy shade, a wide range of soils, and many different temperate zones. The foliage of many hostas is quite attractive, and the flowers (especially those of H. plantaginea) are quite fragrant.
Hosta plantaginea (Hosta, August Lily, Fragrant Plantain Lily)

Extremely tolerant of many soil conditions and climates, hostas are very popular perennials for homes in North America.
Hostas are very commonly used as garden plants for their incredible hardiness. The cut flowers are sometimes used as gifts.
