The days are long enough and the water warm enough to encourage the water lilies to bloom. There are areas in the Brighton millpond where the water lilies are thick.
We have two species on the millpond. The most abundant is the Bullhead Water Lily (aka: Nuphar lutea). The bright yellow orbs appear to be petals, but they are actually sepals, the shields surrounding a multiple of tiny flowers inside them. Once the flowers are pollinated and die, large seedpods form (above). I’ve seen Canada geese and muskrats munch on the flowers so they must be tasty although I’m not sure if they are edible for humans.
The other water lilies are white and look more like lotus, Nymphaea odorata Aiton (below, right). They aren’t as prevalent as the Bullheads but are more popular with park visitors.
