Dear Readers, there are many, many little willowherbs about, popping up all over the place and largely going unnoticed. Broad-leaved willowherb (Epilobium montanum) is one of the commonest, but there are half a dozen others, all going about their business without anyone to celebrate them. So here I am! In urban areas you might also see American willowherb (Epilobium ciliatum) which is usually tinged red. You can see one below for comparison.
My broad-leaved willowherb has popped up in a neglected pot, where it has grown to about two feet tall without any attention whatsoever. As you can see from my original article (below) it is very popular with a whole range of caterpillars, and has been used as a cure for urinary problems and prostate disorders. Different small willowherbs grow everywhere, from the sides of streams to the edges of woodlands, from urban streets to rolling grasslands, and everywhere they go they flower prolifically, with their four pink petals, fires their seeds and then depart, until the next generation arrives in spring. And on this hot summer day (in London at least), let me share a poem by Edward Thomas that seems to sum up the languor of these June days.
Adlestrop
BY EDWARD THOMAS
Yes. I remember Adlestrop—
The name, because one afternoon
Of heat the express-train drew up there
Unwontedly. It was late June.
The steam hissed. Someone cleared his throat.
No one left and no one came
On the bare platform. What I saw
Was Adlestrop—only the name
And willows, willow-herb, and grass,
And meadowsweet, and haycocks dry,
No whit less still and lonely fair
Than the high cloudlets in the sky.
And for that minute a blackbird sang
Close by, and round him, mistier,
Farther and farther, all the birds
Of Oxfordshire and Gloucestershire.
And now, let’s find out what I was writing about back in 2015, when this first Wednesday Weed piece was posted.
Dear Readers, I am always surprised at what turns up along the dark, gravelly path that leads to the side entrance of my house. Yellow corydalis, greater celandine, forget-me-not, buddleia, Mexican fleabane, Canadian fleabane, sow thistle and chickweed all put in an appearance, but this is the first time that I have spotted this little beauty – Broad-leaved Willowherb (Epilobium montanum). I have a garden full of Great Willowherb, but this plant passed me by. It has a delicate, shy habit that means that it is often overlooked but once I’d noticed it, I realised that it was everywhere.
The plant has four, deeply-notched mauve-ish petals, and the stigma in the centre form a distinctive four-lobed shape. The leaves are rounded at the bottom (hence the ‘broad-leaved’), and are practically stemless. Like most of the other willowherbs, it’s native.
As with all the willowherbs, the soft leaves seem irresistible to insects, and the plant that I used for identifications was covered in enthusiastic greenfly. However, the genus is also subject to the depredations of some larger creatures, such as the caterpillars of the Small Phoenix: the Striped Hawkmoth:and, most spectacularly, the Elephant Hawkmoth and the Small Elephant Hawkmoth, shown below:
Plants of the Epilobium genus have long been used as a treatment for prostate and urinary complaints, and indeed a company which manufactures supplements made from willowherb has taken the genus name of Epilobium for its company name (note that this is not an endorsement). Although the showier members of the family are the ones most often used in herbal medicine, Broad-leaved Willowherb was singled out in an Austrian study as having a stronger effect than the others. While there is a lot of interest in Chinese herbal medicine and Ayurveda, herbal medicine in the West is still seen as something of a niche area. Maybe this is because when something grows all around us, it’s difficult to make money from it.
I love Rosebay Willowherb and Great Willowherb. I admire the way that they can take over a spot of damaged and derelict land and turn it into a sea of cerise. But this little plant lurks in the interstices of the city, at the bottom of walls, in the crevices and the dark places, cheering them up with its mauve flowers and graceful habit. And, when the time is right, it fires its fluffy seeds with just as much vigour as its bigger relatives. It might be little, but it’s a plant with ambition.
