An example of the latter is my white rose - a real "Christmas Rose"
It has been flowering constantly since about June last year. Right now the bush has about a dozen flowers on it - though admittedly no leaves! The petals have a distinctive pink tinge to them, especially during the colder months.
Having posted a photo of this on Twitter the other day, I think I have now identified it as "Iceberg". Anyone out there want to give me another opinion?
The reason why I chose the title for this post is that my other "Christmas Roses" - the Hellebores - are just coming into flower now.
Helleborus Orientalis "Red Spotted Hybrid"
I have been looking up the origin of the name. If you are interested, have a look at THIS. Hellebores don't look much like roses as we know them, but I suspect that at the time they were given the nickname "Christmas Rose" they did look more like roses. The rose as we know it today has been significantly altered by selective breeding, so to see the resemblance between a Hellebore and a rose I think we need to make the comparison with the Dog-Rose, which has a much less complex flower structure.
Well, my Hellebores have missed flowering at Christmas by a long way. It seems to take ages for the buds to open. I keep going out to look, hoping that the flowers will be open, but they still aren't!
Looking back at the label from the one I bought last year though, I see that the flowering period is shown as December - April, so perhaps I'm being to impatient...
