That the South uses the word jonquil is quite logic seen the French influence .Both names are right. The French call them jonquilles, the variations: N.jonquilla and N.junctifolius growing wild in South West Europe.

I know the synonym for 'nose' butt... it's nice you use the euphemism. ;-)
And of course we just say :" Lay off daffodil picking!" in imperative non English. Though children like the word Ranunculus. As much as Rapunzel.
