Scientific Synonyms:

Trillium erectum var. sulcatum


Trillium sulcatum is similar to, and was formerly classified as a subspecies of, T. erectum. It is a tall, robust species that will grow to a height of 2'. The specific epithet 'sulcatum' refers to the sulcate sepals, meaning that they curve inward much like the tip of a canoe. The flowers are sit high above the leaves and are typically crimson in color, although due to genetic variations when propagated from seed, can also be creamy-white. The leaves (modified bracts, to be correct), are large, and deeply-veined.


Furrowed wakerobin is easy to grow in deciduous woodland settings, where it gets ample sunlight before the trees set leaf. It does well in average, even rocky, soil. For best performance it should be planted in a moist, well-drained environment, rich in organic material. The blooming period occurs mid-spring, April to May. Zones 5-7


Propagate by division while dormant. Plants propagated from seed can take up to 4 years to reach blooming maturity.

Additional Notes

Both uncommon in the wild and in cultivation, Trillium sulcatum is an exceptional species due to its size and striking features, and is well worthy of of a prominent spot in the shade garden.
