Helleborus, commonly known as hellebore, is a genus of perennial flowering plants in the family Ranunculaceae. These plants are native to Europe and Asia and are known for their attractive, cup-shaped flowers that bloom in late winter to early spring. Hellebores thrive in shaded areas and prefer well-drained soil, making them popular choices for woodland gardens. There are several species and hybrids of hellebores, with Helleborus niger and Helleborus orientalis being among the most well-known. The flowers come in various colors, including white, pink, purple, and green, and some varieties are even fragrant. Hellebores are also valued for their ability to tolerate cold temperatures.
