Toad Lilies

How these pretty plants ended up with the name “Toad Lilies” is not absolutely known.  Some say it is because the orchid-like blooms have spots, although there are many varieties whose flowers are clear, without spots.  Others say it is because toads like to sit under the leaves, but I’ve never discovered one hiding there.  Regardless, toad lilies (Tricyrtis) are members of the large lily family, with the strap-like leaves that characterize that group.  They prefer a woodland setting, in good soil, so give them partial shade where they won’t totally dry out during the heat of summer by adding lots of humus to the soil.  Sight them near a path or bench, where the intricacies of their flowers can be observed, or keep the smaller ones in pots to view up close.  The flowers appear in late summer to early fall, at a time when it is most pleasant to sit in the shade and admire them!


Blue Wonder

There is a range of height in toad lilies, from short to over 3’.  Most form tidy clumps, however a few will spread lightly to become groundcovers.  Nearly all toad lilies are hardy perennials, thriving in Zones 4-9.  However, do check because some species, especially those with yellow flowers, tend to be more tender and often require Zone 6 or higher.  These do make good container plants for northern growers.

     Here are some of the toad lily species and their general characteristics that you can find in the marketplace, the specific selections or varieties are listed under each:
