The Christmas Rose is actually a buttercup. Helleborus niger, known as the Christmas Rose, also has the frustrating tendency of not blooming until Easter - making it all the more confusing to tell it apart from the Lenten Rose, Helleborus orientalis.
Most of the Hellebores on the market now are hybrids. Whatever type you choose to grow, they all share an undemanding ease of growing and a deceptively delicate beauty. They can be a little pricy to buy, but once they're established, they set these plump seed pods and spread themselves about. They can also be easily be divided and make a nice carpet for a shady spot. They're even deer resistant. Try growing a few different hellebores in your garden and see which does best. Then please let me know.
