Hostas are perennial plants, meaning they live for more than two years. The most common type of hosta is the genus Hosta, which is native to northeast Asia. Hostas were introduced to Europe in the early 19th century and became popular as ornamental plants in the mid-20th century. Today, they are widely cultivated worldwide and popular for home gardens. There are more than 3,000 species of hosta, with new hybrids being created every year. Hostas come in various shapes and sizes; their leaves can be variegated or solid-colored. They typically bloom in the summer, producing clusters of white or lavender flowers.
