It’s a complete mystery to me why, of 100,000+ photos of plants in my photo library, I don’t have a single decent pic of Helleborus argutifolius. It more than merits tens, if not hundreds of pics.
Helleborus argutifolius isn’t like most other hellebores. It’s the best known of a small group of species known as the caulescent (stemmed) species that grow upright leaf-bearing stems (while in most other species the leaves emerge individually from ground-level, or underground stems), which terminate in a great cluster of flowers.
Unlike the better known and more florally diverse Helleborus x hybridus (more on them here), Helleborus argutifolius could be grown for its foliage alone, making a great shrub-like mound of leathery, mid-green (and sometimes slightly sage-green) leaves divided into three leaflets, and usually toothed around the edges with benign spines. In winter, each of these stems produces a branched head of Granny-Smith-apple-green flowers, like a great bunch of grapes, with far greater generosity than your average hybrid hellebore.
During flowering, new shoots arise from the base of the plant that will carry the following season’s leaves and the next winter’s flowers. So once the current year’s stems look truly spent (and they go on making a contribution for a very long time), they can be cut right to the ground, leaving the new stems that quickly fill out to replace the old. They’re one of those rare herbaceous plants that really don’t have a downtime.
But better still, Helleborus argutifolius is much more sun and drought tolerant than your average hybrid hellebore, speaking of their Corsican and Sardinian origins. Having said that, Australian gardeners tend to place them in similar shady conditions to the hybrids, in which they flower very well but tend to flop badly. I once used them on a very sunny bank tumbling down to large areas of hot paving surrounding a pool in Templestowe, and I’ve never seen them perform better. The rather shorter stems, due to the challenging conditions, were entirely self-supporting. But that’s the sum total of my experience testing their tolerance. That’s where you guys all come in! Has anyone tested their sun, heat and/or drought tolerance? We need to hear! Please comment below.
