Helleborus foetidus is commonly grown in gardens for its attractive evergreen foliage and abundant green, bell-shaped flowers that bloom in late winter and early spring. It thrives in woodland conditions with deep, fertile, moist, and humus-rich soil. It prefers dappled shade but can tolerate full sun. This plant is drought-tolerant and often occurs naturally on chalk or limestone soils.
One popular cultivar of Helleborus foetidus is 'Green Giant' which has bright green flowers and finely divided foliage. Another cultivar, 'Miss Jekyll', has fragrant flowers, with the intensity of their scent varying throughout the day. 'Wester Flisk Group' has red-tinted leaves and stems, as well as gray-green flowers. The 'Sierra Nevada Group' is a dwarf variety, reaching a height of only 30 cm (11.8 in).
Propagation of Helleborus foetidus can be done through division or by seed. The plant produces a prolific amount of seeds, which can naturalize well in ideal conditions. However, it is important to protect the seeds from rodents, as they may eat them while they are still on the flowering plant or on the ground after seed release.
