John, You can always go on calling your lovely plant Leopard Lily and disregard Belamcanda's unseemly demotion into being just another iris!
Leaving aside the variegated-leaf houseplant Dieffenbachia amoena (which is also sometimes labelled Leopard Lily, though it hardly deserves the name), there is actually a true lily that's the Leopard Lily, Lilium pardalinum - see picture, showing its spots. Unfortunately not a mediterranean plant: even though it comes from California, it grows up in the hills, in the less mediterranean parts. The plants in the picture are growing in fairly moist soil by our pond here in Sussex - very long lived, grown from seed collected by the late Derek Fox in I think 1976 or thereabouts.
