iris tide ...

sprague river, oregon -- Iris is a genus of 260–300[1][2] species of flowering plants with showy flowers. It takes its name from the Greek word for a rainbow, which is also the name for the Greek goddess of the rainbow, Iris. Flowering yellow iris (Iris pseudacorus) at a treatment pond In water purification, yellow iris (I. pseudacorus) is often used. The roots are usually planted in a substrate (e.g. lava-stone) in a reedbed-setup. The roots then improve water quality by consuming nutrient pollutants, such as from agricultural runoff. This highly aggressive grower is now considered a noxious weed and banned in some states of the US where it is found clogging natural waterways. #FootePrintart #art #flowers
