Hostas are one of the best foliage plants for light to medium shade and are deservedly popular. They are hardy perennials, easy-to-grow and good for adding low, leafy structure to a garden. There are many varieties, some growing up to a metre in height and spread, with many subtle leaf variations. Hostas are also valued for their lilac-coloured or pale grey flowers that can be fragrant. They are very popular at the moment as a soft-looking but resilient, large-leafed plant that will add an exotic touch to your garden.
