Toad Lily
Tricyrtis
Toad Lily blooms from September through October.
This entry comes from our curated library and has not yet been independently checked against outside sources. Curated is not unreliable: a standing audit keeps every entry internally consistent, and the source-by-source check is working through the whole library in the open.
Growing Toad Lily
Plant it in part shade. It prefers moderate water. It is hardy in USDA zones 4–8. Expect it to reach about 2.3 ft tall and 1.6 ft wide at maturity, in roughly 2 years.
When to plant Toad Lily
Plant Toad Lily in early spring as soon as the soil is workable, or in early fall at least six weeks before your first frost, so roots establish in cool weather. For the middle of its hardy zones 4 to 8 range, spring means March to May and fall means August or September. Once settled, it blooms from September to October.
Month-by-month timing for your zone is on the planting calendar: for the middle of its range, start with zone 6 in March.
Good to know about Toad Lily
Curated from university extensions, botanic gardens and other primary sources, with the source named on every note.
Worth knowing
A rare autumn flower for shade, blooming late summer into fall, September into October, when little else in a shady garden flowers. That late timing is its signature value. per Clemson and Chicago Botanic Garden
Will it spread?
Sources split on whether it creeps by rhizomes or forms a strict clump, but all agree it spreads slowly and will not overrun a bed. per NC State and Missouri Botanical Garden
Slugs are the main pest
Slugs and snails are the main pest, chewing young growth in the moist shade the plant needs. Reduce debris and handpick; few other insects trouble it. per NC State
Not a true lily
Despite the name, it is Tricyrtis, not a true lily, and is not on the ASPCA toxic-plant list. It has not been formally cleared, though. per ASPCA and NC State
Deer resistant, rabbits browse
Deer generally leave it alone, but rabbits browse the leaves and flower buds, especially tender new growth. per NC State
Never chop mid-season
Do not shear the stems while growing: the autumn flowers form along the upper stems and tips, so a mid-season cut removes the bloom. per NC State
What pairs well with Toad Lily
Good companions share its growing conditions and add something it lacks: an earlier or later bloom, a lower carpet in front, or structure through winter.
Summersweet
Shares part shade and moderate to high water; blooms in midsummer, before this one opens; both offer pollinator forage, in different months; taller at 5.9 ft, for the layer behind it.
Hellebore
Shares part shade and moderate water; blooms in late winter, extending the bed's season; evergreen, so the bed keeps its shape through winter; both offer pollinator forage, in different months.
Rhododendron
Shares part shade and moderate water; blooms in late spring, before this one opens; evergreen, so the bed keeps its shape through winter; taller at 5.9 ft, for the layer behind it.
