Youall would seem to have resolved this one. Thanks.

I'm used to seeing Iris siberica in dense clumps in gardens, so I hadn't
considered it. Stace says that the stems are hollow, and the bracts are
brown and papery when in flower, so I can check these features out if I
have the opportunity.

I've now found another Iris, by another canal. Is this Iris spuria?

Look to me like Iris laevigata.

I also found a lily that appears to have escaped into the wildish. It's
growing in a riverside corridor through a park, but that corridor shows
now evidence of recent cultivation. (The lime trees might have been
planted many years ago.)

Lilium pyrenaicum?

Could well be.
