this just turned up. any ideas?

We moved here in 2012. There were a very small number of sickly/weak cowslips in the lawn. I let the one that flowered go to seed and bought more seed to get a few new patches started, as well as supplement the existing patch. To cut a long story short, they've expanded and larger and larger areas of lawn are being left to grow until they've gone to seed. This year, a new flower has appeared in one of those sections. I think it's a pyramidal orchid but I'm not good with orchids. Anyone know if it is, or if they believe it's something else? Thanks in advance.
