"Kinderkopje" in Dutch is Children's Cups, used to describe cobblestones. In the infamous Paris-Roubaix "Hell of the North" early season classic cycle race it's used to describe the appalling cobbles over which much of the race takes place. Colloquially, they are known as Babies Heads.
Why am I telling you this in an otherwise seemly allotmenting blog? Because the rhubarb stools I've just planted out resemble nothing so much as Hell of the North Kinderkopjes. Here's a pic.
I now have 8 large rhubarb plants, known round here as a Triangle. Surely you've heard of the rhubarb triangle? Hopefully I won't have to harvest it by candlelight, like they do at Oldroyds.
Last year I made a Rhubarb Bellini & commend it to your attention.
