What Is Hellebore Black Death?Contracting a disease called “black death” is almost certainly bad news.
Fortunately, in this article we will not be discussing the bubonic plague, but instead a relatively new and lethal viral disease that affects hellebore flowers.
Hellebores are herbaceous perennials, loved for their winter blooms that pop up in January or February and last until early spring.

In ideal conditions, they are typically easy to care for and will return year after year to provide color in the bleak winter landscape.
Hellebore black death is a devastating viral disease that affects some hellebore species more than others.
Species and cultivars of Helleborus orientalis and H. x hybridus are the most vulnerable, and H. argutifolius and H. niger appear to be less susceptible.
Thankfully, this viral infection is fairly uncommon in home gardens.
While there is no cure, in this guide we’ll cover how to identify the symptoms of this fatal disease.
Recent Discovery of Black DeathSymptoms of this disease were first reported in continental Europe and the United Kingdom in the early 1990s.
Over time, it has spread to the US, New Zealand, and Japan probably via infected nursery stock.
In the US, symptoms matching those of hellebore black death were first observed in a plant nursery in Washington State in 2000.
According to an article published in the journal Plant Disease, in 2009 scientists identified the cause of the symptoms commonly called “black death” as a new viral disease affecting hellebores, and named it the Helleborus net necrosis virus, or HeNNV for short.
HeNNV is classified as a Carlavirus, one of a number

Gloves are always of interest to gardeners – I have an enormous collection, many of which have holes in the fingers, so I think it is time to cull the less than perfect and invest in a few more. I came back from the show with a pair of MechanixWear womens’ leather-palmed gloves (£22) which are soft, comfortable and washable as well as extremely tough. The sizing is on the small side though so it’s best to buy larger than normal. Burgon & Ball always have innovative displays on their stand – their Love the Glove range (from £12.95) were displayed under glass domes. These gloves are ultra-soft but hardwearing, have padded palm and a wrist strap to keep debris out. www.burgonandball.com Sneeboer, makers of fine garden tools have had fun with one of their garden spades that they have fashioned into a stool – it’s not for sale, but I best they get lots of enquiries about it – so who knows, in the future it may be added to the range. Just the sort of thing the hipsters love! Trugs come in every shape and size and the Trugmake
Gummosis refers to the oozing of sap or gum from a tree. This behavior is very common on stone fruits, including apricots, peaches, and plums.You can look at gummosis as your tree’s cry for help in the face of any one of a number of problem
In my earlier post about Sir Paul Smith, I wrote about the role of green as the anchor that holds everything in place in a garden – so it’s unsurprising that the greenness was what I noticed as I looked at some of the drawings of this year’s Chelsea gardens. No doubt, when we get to Chelsea our eyes will seek out the excitement, and the actual gardens will be further enlivened by shape, texture and the play of light, but it is useful to see the contribution that green makes to each of the gardens and bear it in mind for the planting in our own garden.

The Chelsea Flower Show
I don’t think it was just the flat light, grey skies and chilly temperatures that gave the show quite a subdued feel. Of course, it was not helped by our never-arriving spring that has left many of the show gardens with flowers on the point of unfurling, but seemingly as reluctant to open as I was to remove any of the several layers of clothing I was wearing on Press Day.
These gorgeous Black Dahlia Flower Varieties exhibit a deep, dark maroon color, often mistaken as black due to the rich, intense hue of the petals. Grow them in your garden for a majestic display of blooms amidst the lush foliage!
Sir Paul Smith finds inspiration at the Chelsea Flower Show Last week I somewhat reluctantly took the train to London for a second day in a row to attend the late afternoon RHS press briefing for Chelsea 2015. Don’t get me wrong – I was interested – it was the prospect of a two hour journey home on a crowded commuter train that put me off. I’M SO GLAD I WENT.
Retail therapy at RHS Chelsea Flower Show 2014 by Daniel Carruthers The Chelsea Flower Show, now in it’s 101st year, is revered for its wonderful gardens showing the latest trends in garden design. The show does also have many other elements of inspiration too with a wide and often unsung retail section. Predominantly the Eastern Avenue is the shopaholic gardeners first port of call with everything on display ranging from hats and gardening apparel to seeds and works of art.
