Miniature hostas are specially bred to have a height of less than 8 inches. These hostas are perennials and are often used as accents for border or rock gardens that require small plants to fill in the space.
Due to increased interest in this smaller version of the classic hosta, a wide variety of styles exist as of 2014. Miniature hostas require partial sun to light shade. Hostas have shiny, green and sometimes white or yellow foliage, which makes them easy to match with other elements in a garden. Miniature hostas grow best in the hardiness zones of 3 through 9.
