I love my helleborus! I have the traditional Christmas rose ( niger ) and a few un-named varieties the christmas rose is my favorite , the foliage is more compact and stays neater ,my others get very tattered looking. When I first got it it was not happy where I planted it so I moved it . I must have missed a little piece of root because the next thing I knew there was a little one coming up where I had removed it from. This leads me to beleive thatt hey could be easily divided

The Christmas Rose is one of the easier garden plants to grow. Its ability to bloom in the coolest months of the year when everything else is frozen solid make them a valuable asset to any garden. This plant produces flowers from late fall up until early spring. It is an evergreen and grows 12 to 15 inches tall. It has shiny, dark green leathery leaves. Each flower stalk bears a single 2 to 4 inch white bloom (sometimes tinged with pink).
