The hellebore Orientalis, commonly known as the Lenten rose, is an evergreen, late-winter early-spring flowering member of the buttercup family. so it's not really a rose at all. It gets its name because they usually bloom during Lent and they display various beautiful rosey colors in their blooms. They grow hardy in Zones 4 to 9 and can survive in Zone 3 winters.
Their flower pedels hang downward, like those of a butter cup. Flower colors of h.orientalis range from pure white to a deep plum, with in-between shades of pink, rose and magenta. Flowers often show intricate contrasting spots on the inside of each cup-shaped bloom.
