As can be seen here, the flowers are very pretty.
I was intending a picture of the "potatoes" but as so often happens, nature does not stand idle. When I pulled the plants, nearly every one had potatoes hanging from them.
I waited to take pictures until the flowers opened but strangely, when I started pulling them to find a potato to photograph, there were none. I pulled dozens and gave up.
They apparently are absorbed or some such thing when the plant blooms or the few ducks we saw on the pond were very busy indeed.
DUCK POTATOES, The Sequel
Last year I posted the "Duck Potato Story" but as luck would have it, the "potatoes" were gone when I photographed the flowers and plants. I promised a picture of the potatoes this year.
I stand by my previous comments on their being less than a gourmand's delight to eat.
