I garden on a budget so my first purchase of Hellebores were two root-bound pots marked down to $2 at the end of the season sale. They were droopy from poor care and the blooms were dried up so I wasn’t even sure what color they were . I planted them in a partially shaded area and kept them watered. They survived our Zone 5 winter and in the early spring they produced a number of green blossums.
Eventually I grew to really like them. After the blooms dried out they dropped numerous seeds and soon small hellebores popped up. The area I had them became too sunny due to the loss of one of our red buds, so I moved them all the following year. It is best to not move them once they are nature plants, because they develop deep roots that make digging them out quite labor intensive and, if there are tree roots the digging could be a little destructive to your trees. I move them the first year after they grow from seeds because the roots are still small and (like most plants) they adapt to the changes better with less top growth to support. If you have the strength to dig them though, and you don’t have tree roots to consider, you can divide them a lot like a hosta. Get a sharp knife and cut the roots apart leaving at least a couple of leaves at the top, then plant them in the soil and water them well. They do best when given moist soil but I have discovered that they withstand very dry conditions once they are established. They have turned out to be the perfect plant to grow beneath a tree.
The plants stay green well into winter here. They do die back but usually not till February. By March they are starting to put out new growth.
Hellebores can be purchased in various colors and some bloom as doubles. However, if you are patient, you will get different colors over time. The plants I purchased originally looked like the first photo above, but I now have more plants and they bloom in shades of purple, green, and white.
