A tangle of weedy plants near the village green included a solitary plant of the Byzantine Gladiolus, Gladiolus illyricus, subspecies byzantinus (aka Gladiolus byzantinus). I last saw it growing en masse as a cornfield weed in Turkey but it is common over much of the eastern Mediterranean.

The Cornbrook, a tributary of the Cherwell, flows through the village and at its banks near Fiveways is a clump of Yellow Flag, Iris pseudacorus.

It was widespread in the time of John Clare but since then, though perhaps declining in places, it has widely colonised the gravel pits created in the twentieth century.
