Dear Readers, I currently have a lovely young man helping me with the garden – he’s a real wildlife gardening enthusiast, and so we are getting on splendidly. And when I was discussing plans re The Fence, he suggested thinking about this plant – Broad-leaved Everlasting Pea. What a great idea! You can see this plant scrambling vigorously along the side of the South Western trainline from Waterloo to Southampton, and although it is not technically native, it was introduced to the UK in the 15th century, so I think we can assume that the invertebrates are well used to it. What a pretty plant it is! Yes I know it’s a thug, but I have confidence that we can ensure that it has manners.
Actually I am starting to wish that I had a bit more fence, since I currently have about eight contenders for it, including white bryony, which is another splendid plant. Hey ho. I should really have something akin to the Knepp Estate, but sadly I have only a suburban garden here in East Finchley, without room for a single beaver or herd of wild ponies. But what I do have in the way of ‘land’ makes me so happy, especially now I’ve bitten the bullet and don’t feel sad and guilty every time I look out of the window.
And here are a few lines by John Keats. They aren’t about this particular species of sweet pea, but I think they work nonetheless. Sweet peas are so often the first flowers planted by children, probably because the seeds are a good size for small hands to handle, and they grow fast, and smell sweet. They certainly make me nostalgic.
Here are sweet peas, on tip-toe for a flight:
With wings of gentle flush o’er delicate white,
And taper fingers catching at all things,
To bind them all about with tiny rings.
Onwards! Here’s what I said about Broad-leaved Everlasting Pea back in 2016.
Dear Readers, you may often see this sweet pea lookalike scrambling amongst the buddleia between railway lines, or erupting from wasteland beside electricity substations. Here in East Finchley, it is often seen in more weed-friendly front gardens, and if it cropped up in mine I would certainly leave it, pretty plant that it is. Unlike the ‘domestic’ sweet pea, this plant has no scent and is a perennial with a preference for clay soil, largely because although it likes full sun, it requires moisture, which heavier substrates provide. Although in its wild form it is sometimes considered to be a weed, there are also cultivated varieties which are marketed as ‘everlasting sweet pea’. It seems that the dividing line between ‘pest’ and ‘garden plant’ is even more blurred with this plant than with other species.
The ‘peas’ of other members of the Lathyrus genus cause a kind of poisoning called Lathyrism, which causes paralysis of the larynx, excitability, paralysis of the lower limbs and eventual death. Lathyrus sativus, or the grass pea, has been a famine food in several countries, and during the Spanish War of Independence against Napoleon resulted in the deaths of many poor people, as documented by Goya in the woodcut below. The cultivated sweet pea causes a slightly different kind of poisoning, which attacks the connective tissue. Although there is no evidence to suggest that broad-leaved everlasting pea has been implicated in any such nastiness, I’d certainly be very reluctant to ingest any parts of this plant, although I have seen the flowers described as edible.

‘Because of the grass pea’ – this aquatint by Goya shows a woman already crippled by the effects of eating grass pea porridge as a famine food.
Broad-leaved everlasting pea first appeared in cultivation in the UK by the fifteenth century, and had ‘escaped’ by 1670. I am curious as to why it was originally ‘imported’ – many early plants were brought here because of their medicinal properties, or their value as food plants or flavourings, but this plant has none of these benefits, at least as far as I’m able to ascertain. I wonder if its combination of tolerance of clay soils and nitrogen fixing abilities made it a good choice as a ‘green manure’ for improving soils? On the other hand, maybe it was brought here solely by virtue of its hardiness and attractiveness. It certainly attracted the attention of such artists as P.J.Redouté, who is perhaps better known for his nineteenth century paintings of old-fashioned roses.
So, next time you are sitting on a crowded train heading out of London Bridge or Waterloo stations, have a look at the mass of ‘weeds’ growing at the junctions between the lines. I can more or less guarantee that somewhere there will be a neon-pink tangle of broad-leaved everlasting pea brightening up the place. It’s amazing what you can spot during a commute. It’s almost worth bringing your binoculars.

At first I wondered if the wasp was planning on munching on the aphids, but after a while I realised that it was much more interested in the honeydew – the ants who were ‘farming’ the aphids didn’t like this, and would drive the wasp off whenever it tried to land. Eventually the wasp gave up and sat on a self-heal leaf for a bit. In the photo below you can make out that shiny red bottom.
What fascinates me is how a tiny collection of ten meadow plants can become an ecosystem in just a few weeks, and this was after less than twenty minutes observation. Who knows what else goes on? And I am full of questions – why is only the goatsbeard covered in aphids, and everything else looks fine? Are these the same ants that have recently put in an appearance on my living room floor? And what will happen after I’ve washed the aphids off? I shall keep you posted…
