Yellow flag iris is widespread across England and Wales, where it's found in a wide range of damp places. It's a lovely architectural plant for the pond or river edge, where it will grow to 1.5m. Yellow flag iris is one of the more vigorous plants we sell, spreading naturally or via its very large floating seeds. Its lovely yellow flowers go very well in any planting scheme with dark blue, and are the origin of the heraldic fleur-de-lys. "Flag" comes from the middle English word for a rush or reed, "flagge".
We offer Yellow flag iris as either bare root or in 4cm or 5cm plugs, depending on availability.
Please note that these plants are only available on a seasonal basis. The nursery grows new stock from autumn to early spring, so we do not deliver over this period.
