I don't have an explanation why they are not more common with popular mail order sources. They are pretty widely available in my area at local nurseries and garden centers but purchased in from large wholesale growers for resale. And tend to be a very seasonal item as well (as are all other hellebore varieties - not a stock perennial).

All that I have seen over the last few years have been named forms, developed by the massive German plant breeder Heuger Gartenbaubetriebe, and sold under the trademarked name of HGC or Helleborus Gold Collection. They offer a bunch of nigras (7) with cultivar names like Jacob, Joel, Jasper, Jonas, Jesko......and Diva and Wintergold.

To be honest, based on my personal experience in the retail nursery industry and as a former perennial buyer, these hellebores are not nearly as popular as the much more colorful xhybridus or the newer interspecific hybrids. They seem to appeal more to serious hellebore aficionados and collectors rather than the general gardening public. And to be fair, nigras tend to flower so early in the season, they are often buried in snow in colder climes. But the plants are out there and to my knowledge, unaffected by any pathogens.

No, they aren't. Here, they flower in March, and while they may get snowed on, March snow doesn't stick around. They aren't more likely to be buried than the early crocus, and less likely than snowdrops.

While that may be true where you live, mad gallica, I am not sure that is consistent with everyone's experience. They are not commonly called Christmas Rose for nothing! In an article written by Margret Delves-Broughton, she states: "the best thing about my beloved Helleborus niger – it blooms in December. In fact, it’s loaded with buds in my northwest Connecticut garden right now (article was written on November 16th). It has blossomed every year that I’ve had it at this time, though I must add that some years we’ve had snow cover by this point so technically, I can’t verify that it bloomed during those winters. Any new gardener will laugh when they hear that the first few times it bloomed in December, I asked other gardeners what they thought was going on. Most of them looked at me funny and said that the plant must be “confused.” It turns out that it’s not confused – it’s supposed to do this! According to the Missouri Botanic Garden, “Helleborus niger, commonly called Christmas rose, is a winter-blooming evergreen perennial which blooms around Christmas time in warm winter regions, but later in the cold northern parts of the growing range…. Flowers sometimes bloom in the snow and bloom can survive spurts of sub-zero temperatures.”

So this must be different definitions of 'later', 'Christmas', and 'November'.

I thought they were called Lenten rose. Which makes sense where I live, they usually bloom somewhere around this time, March or so. Mine got smushed by a heavy, wet snow this year, they're looking pretty sad. Eh, I can't really see them well from the house anyway, so I don't really care.

O, I think it is just fashion, David. A while ago, hellebore niger were largely superceded by various hybrids(ericsmithii, nigercors etc.) and the varied colours of highly bred hellebore orientalis. Imade a rather long car-trip (for me) to buy a single yellow-flowered orientalis in bloom. Not that much call for a plain white, single h.niger (although I dearly love my sole Potter's Wheel and some seed raised 'children of Ushba' plants from Derry Watkins 'Special Plants')...which have been blooming since late January/early Feb - certainly not around Xmas.

I tend to avoid doing all that chopping back of foliage on the h,nigers since they are never as vigorous as the orientalis, so I tend to leave them be to get as much energy as possible via the (often tattyish) foliage. Might be the wrong thing to do but hey ho, that's where I am at.

Can you identify these two Hellebores? I have a pink one, purple one and one that has greenish-cream flowers, and YES, I have some these bloom here in NJ in December and throughout the winter, I just am not out the yard usually looking for blooms in the Winter. I love this genus of plants, not too much in full bloom in early to mid winter here.

Thanks for the replies! I am relieved there isn't some nefarious reason (like a virus) that they have become uncommon.

THEY ARE EXPENSIVE, could be a reason!

" I thought they were called Lenten rose. "

That is a different type of hellebore. Nigra is often called Christmas rose because it is one of the earliest to bloom........typically in December in its native environment as well as in local gardens.

Lenten rose is the common name applied to orientalis and the orientalis hybrids (xhybridus). I'd guess they may well bloom at Lent in colder climates but they have been blooming for months here.

I don't find hellebores to be any more expensive than most other evergreen perennials. Most are around $17-25 for a gallon sized plant in full bloom. I just bought some lupine that were $18.99/gallon!

Zounds!! And I thought west coast plant prices were high!!

Just bought 5, 3 gallon sized pieris for a new planting I am doing and they were $49.99 each. $50 bucks for a one gallon would be something you see here with Japanese maples. Never perennials.

No idea why they are so $$$ here, but they ARE!, and perfectly hardy here.

Most perennials are in the $25 to $35 range for a one gallon size. Hellebores are painfully high.
