Purple Autumn Crocuses

I found a large group of these beautiful crocuses growing together, next to a bench, on a small green in the village of Boughton Monchelsea near Maidstone in Kent. I think the species of crocus looking fine and lovely and on display here is Speciosus but I’m not 100% sure because I am no flower guru. However, there is some evidence on display in these photos – the dark purple veins marked on the petals and the orange stamen are all indicators this is the crocus in question.
