Northern Marsh orchid
A little past it's best, but it's been the first time I have been to the park in a while, growing not far from the stream that runs through the joining of the two parks, placed it on iSpot and it has come back as Northern Marsh orchid ( not 100%) . It's the first time I have recorded Orchids at the park, there are two theories to why it might be here, the floods last year could have washed it down from the hills last year, as they are on the Chevin. Last year they dug a new path through from the playing fields, from past experience I have been surprised what grows when they move the soil.
note there are no spots on the leaf, this still is not a conclusive ID tool as Orchid are often a mix of two.
