Grey trunk, long thin leaves, certainly sounds willow like.
But I know not a variety with 12 inch long leaves

S. viminalis can get there, and there may well be cultivated varieties
or non-native species that get over that.

Not that I know much about them, is Eucalyptus a contender?

A good point. Yes.
