20. Toad Lily
We talked about lilies, but this is one of the unique tubers you can find. Many believe they are one of the most exotic flowers because of their looks and design. They tend to bloom much later than most flowers, which can add a new kind to your garden. Their peak times are between August and September but can come as late as October.
Their spread is about one to two feet, and they can grow from two to three feet. They are commonly found in southern and central Japan, especially around sun-shaded cliffs and stream banks. They usually have about six petals, but a few grow more or less.
