Since I have so many Toadshade on my property (probably 100-200 each spring!), I have transplanted several to my wildflower garden. I have found that they do very well; the ones I planted last spring have come back & new ones also sprouted (they spread). But you do have to be sure and get the entire bulbous part of the root when transplanting. The plants need shade & moist, well-drained soil, rich in organic matter. They will tolerate some sun, but is best if sun is filtered or dappled through the canopy. All of last year's Toadshade were burgundy-flowered, but this year we have many with yello-ochre colored flowers. Ours grow 1-2 feet tall, rather than the "under 6 inches" listed in the profile. The wooded portion of our property has been undisturbed for many years & is a wildflower haven.

This plant is native to the southeastern portion of the United States. It flowers reliably and produces bulblets which can be separated to start new plants. It is best to divide in the fall. The foliage is outstanding and is almost as much fun as the flower itself.

Not the easiest of plants to grow, like most wildflowers. It is a spring ephemeral, so it will disappear after blooming. Flowers can be inconspicuous, but if they are happy they can put on a show. I just happen to like wildflowers, and their habitat is quickly disappearing. Worth the effort if you like the unusual.

These woodland plants are often considered endangered in their native habitat; purchase from reputable nurseries.
The plants flower in early spring, but unlike other species, the flower is inconspicuous, and the mottled foliage is generally noticed first.
