The production of this variety of asparagus, from growing to picking, must take place in a defined geographical area in the region of North Rhine-Westphalia along the Dutch-German border. The region's sandy soils were once considered by local farmers to be a major disadvantage, but when Major Walther Klein-Walbeck first attempted to grow asparagus around Walbeck castle in 1923, they quickly changed their minds – the local climate turned out to be ideal for growing asparagus.
