What's the Scoop on Hellebore?
Hellebore Undergoing Color Transition: Transformation from Pink to Green in Hellebore
Got a curious garden friend blooming green instead of the usual pink or white? Don't fret! You're not growing some strange mutant; it's just ol' reliable Hellebore at its advanced stage.
Let's dive into the juicy details about this delightful perennial flower and its peculiar color-changing act.
The Lowdown on Hellebore
Hellebore, a group of various species, delights us garden folk with early-blooming flow-eros. In balmy climes, they'll brighten up your garden during December, while colder regions will delight in their presence from late winter to early spring.
These plants, looking like cute little clumps, grow low and steady, with show-stopping blooms popping up above. The flowers mimic roses, boasting a range of colors that deepen as the plant grows older – white, pink, green, deep blue, and even yellow.
The Secret Life of Green Hellebore
Its unique changing color feature sets apart hellebore from other flowers. So why do these blooms turn green while most plants start out green or another color? As it turns out, it's due to the fantastic process of senescence, or the programmed death of the flower.
When the flower first pops its head out, it presents its primary colors, such as pink or white. But as it grows older, the initial pigments fade, and chlorophyll, that green stuff, starts to show off. Now, you might be thinking, "Isn't chlorophyll for leaves?" Well, my friend, in hellebore, it's indeed in the petals.
It's worth noting that what you see greening isn't exactly the flower's petals – it's the sepals, those leaf-like structures surrounding the flower bud. In hellebore, they're known as petaloid sepals because, well, they resemble petals. The greening sepal spectacle may enable the hellebore to conduct more photosynthesis, perhaps even late in the game.
Determined researchers have discovered that the greening sepals are part of the flower's senescence process, as well as some chemical changes that accompany the color change. These alterations include a decrease in smaller proteins and sugars and an increase in larger proteins.
While the reasons behind the color shift remain unclear, one thing is certain – the flower is winding down and probably not attracting as many pollinators as it once did.
