I have grown these, but the blooms of the cultivars I am familiar with are really tiny yellow leopard spotted flowers – I misjudged the scale (seems a full square from an A4 makes quite a sizeable bloom)

A delicate, spidery flower, with a well developed nectary and some interesting folds – if I was to fold it again I have learned what does what so I think the second+ fold would be much better

You too can have a go – it is not that difficult: goldenslipperorchid
