What is stippling? The term stippling or stippled describes the dot-like patterns produced in nature on the flower. Stippling dots can be so profuse that they produce a pattern on the petal bases and sepals. (It's the same concept as stippling in the art world -- kind of like the technique Monet used in his paintings.)
As far as stippling goes, many daylily growers are either lovers or haters -- I'm in the love group!
