Here is a chance that few ever get. What really lies beneath the surface!!! The rhizomes are BARED!!!
Get the skinny here> Nuphar luteum ssp. polysepalum
Thanks Gin.
Most of the images on the net only show floating flowers and leaves but the plant is not really shown. So I figured that since I needed to deal with the failure of the old cow trough that it would make an interesting read as well as give one and all a good look at the plant itself!!!
