Helleborus orientalis is another perennial garden plant and is a member of the buttercup family. It likes the shade and rich, moist soils. Its cup-shaped flowers can range from green-white to dark purple and its flowering season can start as early as February. It is poisonous! Do not nibble! My great-aunt collects them, not because they are poisonous though, don’t call her a witch or she’ll turn you into a newt SHIT SHIT I DIDN’T SAY THAT
