About hose-in hose concept (for a different flower, primula, but the same idea):
Originally, this flower variant was given the name Hose-in-Hose because the form of the flower is reminiscent of the way some Elizabethan gentlemen used to wear their stockings, one inside the other with the outer stocking turned down. The origin of the name gives us an idea of the antiquity of this type of Primula and in fact John Gerard makes the first recorded mention of a Hose-in-Hose flower, in his 1597 herbal. Parkinson also mentions the variant and illustrates it in his ‘Paradisi in Sole’ in 1629.
