Church plant sales aren’t uncommon but I’ve never seen one in London before, especially in a location as grand as the St Pancras Parish Church. There were all kinds of plants on sale – roses, African violets, dahlias etc – and the man selling them told me that the money goes towards planting the church garden.
I was charged a rather steep £7 for a houseplant for my desk, but we’ll gloss over that as it’s for a good cause.
