Hellebores are known for blooming at major holidays. I have had this one in bloom as early as Christmas in freakishly warm years.
This one blooms later. Technically it is supposed to be called the Lenten Rose. It’s just squeaking in under the wire since Lent ends in a few days. But then again, up until a few days ago, we have had an abnormally cold March and April.
These plants are tough (I have had snow all over the white one and it just bounces right back!), deer resistant, and the foliage is evergreen (when not snow covered.)
There are some cultivars that are much more exotic than these, with flowers that absolutely dazzle. If you don’t grow these plants, consider adding some this year!

That’s quite a range for bloom times. Lovely. Hellebores have done exceptionally well here in NC this year.
It’s not always that their bloom time is as varied–or as long. I think a lot of it depends on whether you have the alleged Christmas rose or the Lenten rose. And of course the always unpredictable weather!
Thanks for reading and commenting!

Ah, hellebores! So lovely…. *sigh*.. and as Dorcas Lane of “Lark Rise to Candleford” might say: “They’re my one weakness”. 😉 (along with all of the other horticultural weaknesses I am heir to, LOL)
I am very fortunate that they don’t grow better for me😊.
