Hello, I'm putting together the list of characters in an old English pantomime to be performed in Germany. Three of them are girls who work in a garden: Rosa (who waters the plants), Violetta (who sows flower seeds) and Colombina (who picks weeds). Would it sound OK if I identified them as Giesskannemädchen, Samensäerin and Unkrautjäterin ? I don't necessarily need professional gardening terms, it would be better if they sound charming or even comical. Any corrections or suggestions are welcome!
