Bought this plant in spring of 2011. Sat quietly in semishade most of the summer. But began to grow in cooler, wetter days of fall, got multiple buds in December and opened to beautiful striated pink blooms in January. Blooms sit upright above plant so you can appreciate how lovely they are. Continued to gradually change colors (antiqued) and are still open, plus has rebloomed in the middle of April(at least four new blossoms), although colors are not as striking as the January blooms. Love the wine red stems and the bluish- gray, slightly veined leaves. Has spread to 12 inches in one season. Was looking forward to seeds, so I am glad I was advised to divide it instead. Bought one other one to add two days ago.
I just love this hellebore and am taking out some of my older orientalis -to be shared with friends- to make room for my new favorite.

I bought several pots of these 'Ivory Prince' hellebores about four years ago and I can say they are simply stunning and the easiest hellebores to grow in my garden. They have not seeded and I think you may have to divide them to get more. Which is too bad because I wish they would spread faster! The white flowers are a never fail in my garden in nearly full shade conditions in Zone 7A in the February/March time frame. The leaves are much stouter and more attractive than the normal orientalis species. Easy care and drought tolerant. They stay short overall but the flowers are slightly above the foliage and very easy to see. Stunning hellebore!

I too live in Michigan and just bought this plant and the tag on it says partial to full shade so mine is going in my shaded area. And from experience I would say shaded would be the best since I have a Hellebore Orientalis and have it in my shaded area and it thrives.
Love these plants they are the most forgiving plants to grow they just are very easy and hardy to come back and better than ever every year.

I agree, a great little plant! Blooms lasted from March thru mid-September and the leathery leaves stay upright and attractive even in the Michigan winter snow. Front-facing flowers don't droop like other helleborus I've seen. Hope to put in more this spring.

What a great little plant. I live in Zone 4, at 7000' ft elevation, extreamly dry conditions, with persistant deer and elk populations. This plant has surrvived all of these challenges, and come back more beautiful each year. I think that it is the most under-appreciated perennial on the market!

I have not had this plant long enough to rate it except for the beauty of its changing bloom colors and blue-green foliage on wine-red stems. Bred by David Tristram of England, this is a cross of a cross of a cross. Its a cross between Helleborus niger and another hellebore that is a cross between H. niger and H. x sternii. H. x sternii is a cross between H. lividus and H. argutifolius. It is disease resistant as well as rabbit and deer resistant. The flowers are unusual because they face up and outward from the plant and are flat so the complete blooms are easily seen. Propagate by dividing in late spring to early summer.

WARNING: Hellebores are poisonous.

All around beautiful. Flowers slowly change from green to ivory to pink, foliage is an amazing blue-green with reddish stems. Bought one last year overwintered fine, put in two more this year. I have it in partial sun, zone 5.

Note - this is a sterile hybrid, so if you want self-seeded colonies of hellebores Ivory Prince is not a good choice. But they do form vigorous clumps, I have yet to divide.

Just a start.

Bought 5 Ivory Prince at White Flower Farm's sale a few weeks ago. They are in the - what - 2" pot sold by mail order and were just $2 each. Shopping gene took over.

Love the small bluish leaves. Wonder how long before they bloom. Patience required. That, and actually planting them.
