Toad lilies (Tricyrtis) are perennial plants native to east and southeastern Asia. Their preference for shade coupled with their late and interesting bloom has won them favor for the garden. They produce stems of ladder-like foliage, somewhat reminiscent of Solomon's seal (Polygonatum) and fairy bells (Disporum). They flower in late summer to autumn, with interestingly patterned orchid-like flowers.
Although toad lily flowers may look delicate, these perennials are actually fairly easy to grow.
Toad lily tips:
Most toad lilies prefer partial or full shade, but some varieties tolerate full sun. (With more sun, they will require more water.)
The prefer humus-rich soil that stays slightly moist but drains well.
Toad lilies can tolerate some drought once established, but the tips and edges of their leaves may turn brown in dry times.
Hardiness varies by species and cultivar, but in general you will find toad lilies rated winter hardy to USDA Zone 4 and warmer.
In the colder end of their growing range, plant them in a southern exposure so they will break dormancy early enough in spring to develop and flower before the fall’s killing frost.
Toad lilies spread by underground stems, something to keep in mind when choosing a location and companion plants.
Rabbits may eat these perennials, so use wire fencing and/or rabbit spray around them where rabbits are common.
Good companions include hosta, Solomon’s seals (Polygonatum) and astilbe.
