Although it looks as if it could have been Photoshopped for a sci-fi cartoon, the toad lily (Tricyrtis hirta) actually comes from moist woodlands and high elevations from Eastern Asia to the Philippines. Its unfortunate common name, the toad lily, refers to the frog-like blotches and markings on the flowers. This is misleading, since the bright purple markings on the flower are intriguing rather than toad-like. The funnel-shaped white flowers are spotted with vibrant purple spots with matching centres. The stems are leafy and arching.
Despite their exotic look, toad lilies are easy to grow. What makes them a special perennial is not only the bright, unique flowers, but also their ability to bloom in shade from late summer to early fall. Not too many plants provide bright colour in the shade this late in the season.
The toad lily grows 60 to 90 cm high and 45 to 60 cm wide in zones 4 through 9. They can be used as an accent, a cut flower or in a woodland garden. Gardeners note that Tricyrtis hirta should be planted where they can easily be seen.
Master gardener Merle Burston chose the specific variety Tricyrtis hirta ‘Miyazaki’ in Gardening from a Hammock. “The starry, burgundy-spotted white flowers of the toad lily bloom down its stem in autumn,” she explains.
‘Miyazaki’ is a slightly smaller variety, 45 to 60 cm high, with a 45 to 60 cm spread. It grows in a compact green mound. The flowers of the toad lily have both male and female organs and are pollinated by insects. The clumps can be divided in early spring.
