A question in response to last week’s post about hellebores has prompted this one. Linda (who blogs at https://shoreacres.wordpress.com/ ) made this comment: ‘What really surprised me was finally figuring out that the green was a sign of aging rather than a sign of ‘youth.’ I assumed the petals were green at first, and then turned rose. But from what you’ve said, the fresh petals are cream colored — is that right?’

In my reply to Linda I said that the flowers turn green as a part of the aging process. Sometimes, however, there is a slight blush of green on the younger flowers too. (That green shows that there is chlorophyll present, which contributes to the plant’s overall photosynthesis.)

The ‘petals’ of a hellebore are actually sepals. That’s the part of a flower that is normally green and leaf-like, and sits behind the petals. The hellebore sepals turn green after the flower has been pollinated. Some hellebores have sepals that age and darken to a peachy-pink shade, as you can see in my top photo. Whatever their colour, the flowers can last for weeks, with the sepals being more robust than normal petals.

You might be wondering why the hellebore has no true petals. In fact, they’re still there, but over time have evolved into the tubular structures arranged in a ring in the centre of the flower. These are the nectaries, which produce nectar to attract any of the wild bees and other insects that may be active during winter or early spring. In the photo above, you can see the ring of nectaries is still on the old flower, but the stamens have dropped off after pollination.

In the bottom photo, you can see that the nectaries have now also fallen off this old flower. That leaves just the carpels that contain the developing seeds in the centre. How different the aging flower looks compared to the younger ones below it! Those still have both their stamens and their nectaries. (In this case I think the nectaries very pretty, like little ruffles with delicate pink stripes inside.) This particular plant does have a greenish tint to the cream flowers, which later become a vivid green.

Oh, and just to confuse things a little, there are green-flowered hellebores. Helleborus viridis and Helleborus foetidus are both native to the UK and have green sepals throughout their flowering period. Then there’s the Corsican hellebore (Helleborus argutifolius), also known as the holly-leaved hellebore because it has spiny leaves. This one has attractive lime-green flowers and I’m tempted to try growing it, both for the novelty of green flowers and for the handsome foliage.

It’s been wet and miserable outside for a few days, so there’s not much temptation to go outside. However, now there’s a little treat for every time I venture out into the garden. The slight rise in temperatures has encouraged the hellebores to begin to bloom, giving some bright colour under the grey sky.

The photos here are both of the same hellebore – ‘Rosali’ – although the flowers look rather different. (I’ve used photographs from previous years because the flowers of this one are still just in the process of opening.) Looking at the flower colours, you might think they’re different plants, but no, they’re the same one. I must admit, I did wonder if they could really be the same, but last year’s post of Rosali’s flowers convinced me.

I think the difference in appearance is due to a combination of things; variations in the plant from year to year, flower age, and the effect of lighting. The flower in the bottom photo is aging, and you can see the green creeping into what had been the cream colour of the petals. On the other hand, the top photo is of a fairly newly-opened flower, which will probably become more cream as it develops. In the photo, the crimson which usually just edges the petals shows through the whole flower. Probably this is because of the way the strong sunlight is lighting the flower from behind, carrying the deep colour of its reverse right through it.

Earlier I went out to check on this hellebore and was delighted to see a generous mass of dark-coloured buds, with just the first few starting to unfurl. Soon it should have lots more flowers open – enough to make a winter day feel brighter and spring just a little bit closer!

During the run of frosty mornings this week, I spent a lot of time photographing plants in the garden. While busy in amongst the icy foliage, I looked down by my feet and noticed that even the hellebores appeared to be frozen. I haven’t seen them frosted before because the areas they’re in are usually too well-protected by nearby shrubs. To my fanciful imagination, they look as if they’re all tucked up, sleeping soundly and waiting for warmer weather.

These hellebores manage to be in flower very early in the year and their presence reminds me that winter won’t be here forever…spring will come! As it happens, the flowers appear to have emerged slightly earlier than they have in previous years. (Up until now I’ve seen them in flower here at the start of February. Perhaps the earlier flowering is because the plants are now becoming more established.) It was still less than halfway through January when I photographed them, so there is likely to be more cold weather for them to face.

Freezing temperatures don’t seem to bother these tough little plants, despite their glamorous appearance. I’m grateful for their resilience. It would be wonderful if all the rest of the plants in the garden could be relied upon to come through winter so well. (But I can only blame myself for the less hardy plants chosen for here. And what would life be without the excitement of a little bit of risk…?)

Frost gives me good opportunities for garden photography in winter, but it’s generally not good news for the flowers in my pictures. The rose photographed last week was robust enough to survive, although it may not open any more fully. Most frozen blooms, however, are left with wilted and sagging petals when they thaw.

That’s not a worry, since the frost will usually just have finished off the last of the flowers from autumn. The plants will flower again next year – if they’re hardy. But there are some that are only borderline hardy and will only survive if the winter doesn’t get too cold for them.

The salvia above (Salvia involucrata ‘Bethellii’) may withstand temperatures down to about -5℃ and this plant managed to come through several winters. A far colder spell than we’ve had for a long time was too much for it, though, and it didn’t reappear the following spring. Some cuttings from the plant did survive that unusually cold period. They are in a huge pot that’s part of a collection of containers that my husband has planted up to go in front of the house. There it’s sheltered by the house wall. It benefits from a sunny, south-facing position and the warmth that radiates from both the wall and the paved driveway below it. This just shows how microclimates can vary within a garden!

The little daisy below was, I think, Rhodanthemum ‘Moondance’. (The leaves belong to the plant behind it.) It should have coped with winter. In this case it was probably the heavy winter rain that killed it rather than the cold. It’s a Mediterranean plant that likes good drainage. Here our summers are normally very dry, but, awkwardly, our winters can be rainy and wet. That means that I do sometimes lose plants if I haven’t given them good enough drainage. I think I’m lucky that so much does survive! 🌿
