I have a longstanding amateur interest in British herbs and wildflowers. I've recently reflected that one of the things that really bothered and disappointed me about TSP even before all the scandal blew up, was SW's generic style of writing about plants. You'd think that growing up on a farm, and later living in the Welsh countryside, SW would have some close up knowledge of wildflowers, herbs, etc. Yet nothing indicating any real personal knowledge of or curiosity about wild plants and their properties comes across in the books. It's the same in Saltlines (you can see much of her prose for this for free on the Bandcamp Gigspanner page: https://gigspanner.bandcamp.com/album/saltlines )
Even when she does talk specifically about plants in Saltlines, it's purely a generic list of names of vaguely coastal plants such as you could find in any reference book. For instance in The Pollen Path:
Cow-parsley, clematis, achillea, elderflower, and heather.
Clover, bluebells, thistles, and nettles.
Royal fern, willow herb, alexanders, comfrey, and tamarisk.
Stitchwort, gorse, hawthorn, and wild garlic.
Water mint, thyme, samphire, and wild strawberries.
Quite an odd list - she is describing these plants as if they were seen on a specific walk she has taken, yet they are not plants that all flower at the same time and some of them grow in widely varying environments. That might not matter if she was trying to eg mystically depict a long path in all seasons. But what I'm left feeling is that she really doesn't know much about any of these plants, and has no real curiosity about them. Also I can't recall any place in TSP where she really describes a plant in any detail to make us see it, beyond telling us its name. This was one of the things that made it ring hollow to me from the start - it reads as if written with a reference book to hand, slotting coastal plant names into a route.
I wonder if others have also felt annoyed and let down by TSP's generic approach to plants in particular? It was one of the things that made me question the whole book.
