They are late-winter/ early Spring-blooming, shade-loving perennials with pleasant foliage.
Heronswood offers a number of varieties. So does Bluestone.
Some varieties bloom in the snow, long before spring bulbs.
Here's how to take care of your Hellebores. Seems like a good idea to plant them in bunches. (In our view here at the farm, there are only two types of planting plans - massed - all of one species - and specimen plants. Random mixes are just a mess, we believe, most of the time. I violate the rule often)
I am going to get me some and see how they do.
(I wonder about the impact of online plant sellers on local nurseries and the old standard plant mail-order catalogues. Must be like the impact of Amazon on booksellers. Nurseries cannot compete with the online selections. Just look at Hosta Patch - 500 varieties of Hostas.)
