Helleborus torquatus is arguably one of the more controversial 'species' and it
is very possible that the name will be revised or disappear from official
nomenclature as we know it. Originally, it was described as a plant with dark
flowers. Perhaps inconveniently, the plants in wild H. torquatus populations do
not comfortably fit the nomenclature. Distinguishing between H. torquatus and
Helleborus multifidus has particularly proved difficult. Both have repeatedly
divided foliage and flowers can at times be nearly identical. Northern and
southern populations of what we refer to as H. torquatus also show significant
differences. A revision in this part of the genus is underway, but for now I will
keep the H. torquatus name as is. I will update or replace this page as
changes occur.

Horticulturally, these plants are very attractive but can be slow to mature.
Placing the plants in an open position where some bright light is available will
lead to faster and more floriferous growth. The sepals may be dark violet or
green on the interior and are frequently dark colored on the exterior. Bracts
may also have dark markings. Mature plants also can produce heavily divided
leaflets, making it an especially useful foliage plant.
