I used to have a broad-leaved sorrel in the old garden, and the chickens were the only members of the household who enjoyed it. I briefly had one in the new garden, but it always looked awful and we didn’t eat it, so I removed it.
I also had a Buckler leaved sorrel, which looks more delicate and has smaller leaves, but is a wild, spreading beast of a plant. I removed it, too.
It had other ideas, and is now springing up in the perennials bed it was originally planted in, and in the blueberry bed next door. I can take a hint, so I am harvesting a handful of leaves at a time to add some zing to salads.
The broad leaved varieties are better for cooking, not least because it’s easier to pick a good wodge of leaves! So maybe one will make a reappearance in the garden one day. Who knows? Either type is easily grown from seed, or you can pick up plants at good garden centres.
