Uniquely identifiable characteristics

Distinguishing Feature : The extreme length of the single trumpet shaped flower rising almost directly from ground level to about 6cm, a unique feature.

Not to be semantically confused with :  Koch Snowflake [a geometric structure with similar name].

So rare it is omitted from most UK wild flower books. Originally known from the Alps where it avoided growing on chalk soils (a calcifuge - a chalk hater) it was planted in parts of Surrey in 1960 and now grows wild on chalk grassland as a calciphyte (chalk lover)! Only found in one single hectad. So it looks like it has the genes to enable it to swap allegiances between liking or dis-liking soil alkalinity, an adaption which enables it to grow on both types of soil given enough time to 'acclimatise' itself.
