This Blog contains Wildlife and Bird Photos from Walks, Safaris, Birding Trips and Vacations. Most of the pictures have been taken with my Nikon P900 and P950X cameras. On the right of the page are labels for each species of Bird/Animal etc. Click on a label and it will show all of the photos taken for that species. I am adding as much information for each species as I can from sources Wikipedia. To see any pictures at full size just click on the picture.

26-3-2023 GANDIA MARJAL, VALENCIA - YELLOW IRIS (Iris pseudacorus)

Iris pseudacorus, the yellow flag, yellow iris, or water flag, is a species of flowering plant in the family Iridaceae. It is native to Europe, western Asia and northwest Africa. Its specific epithet pseudacorus means "false acorus", referring to the similarity of its leaves to those of Acorus calamus (sweet flag), as they have a prominently veined mid-rib and sword-like shape. However, the two plants are not closely related. The flower is commonly attributed with the fleur-de-lis.

The plant was rated in second place for per day nectar production per flower in a UK plants survey conducted by the AgriLand project, which is supported by the UK Insect Pollinators Initiative. However, when number of flowers per floral unit, flower abundance, and phenology were taken into account, it dropped out of the top 10 for most nectar per unit cover per year, as did all plants that placed in the top ten, with the exception of common comfrey, Symphytum officinale.

9-3-2022 ULLAL DE BALDOVI, VALENCIA - YELLOW IRIS (Iris pseudacorus)

It used to grow in the ditch of the fortified city of Mdina, on the island of Malta, where water was readily available, but after the renovation of the ditch it has since vanished from the area.

In some regions (including the US and South Africa) where it is not native, it has escaped from cultivation to establish itself as an invasive aquatic plant which can create dense, monotypic stands, outcompeting other plants in the ecosystem. Where it is invasive, it is tough to remove on a large scale. Even ploughing the rhizomes is often ineffective. It has been banned in some areas but is still widely sold in others for use in gardens.

Iris pseudacorus is reported as invasive in Connecticut, Delaware, Maryland, New Hampshire, New Jersey, North Carolina, Oregon, Tennessee, Virginia, Vermont, Washington, Wisconsin, and West Virginia.
