At the end of the summer, beginning of fall there are some hostas that are just beginning to bloom. Many of the late summer blooms are dark purple in color or are fragrant. Fragrant hosta blooms are usually larger in size. Some are so strong that you just have to walk into the garden to enjoy their scent. The scent is much like a lily of the valley. Like lily, hosta flowers are more fragrant in the late afternoon/evening. Some, like plantiginea, only bloom in the late afternoon/evening. Hosta plantiginea has blooms that are up to 4 inches long, and is the mother of all fragrant hosta available on the market. Here is a list of hosta with fragrant blooms: Fragrant Blooming Hosta List.
