Hellebores used to be the domain of specialty plant collectors, but recent hybridizing has introduced several varieties that are easy to grow and are readily available in garden centers. The three most familiar species are H. orientalis (often called Lenten rose), H.niger (commonly known as Christmas rose or black rose), and Helleborus foetidus (commonly known as stinking hellebore). Varieties labeled as Helleborus x hybridus are generally hybrids that have H. orientalis as the principal parent.
