Andy, it sure looks like Columbiana to me. Although lately, I have been thinking that there is a Columbiana complex, like there is with Gen. MacArthur and the MacArthur complex we discuss. What's with the second croton?
Don't look like Columbiana to me, way too much color. Looks like it is in the Father's Day complex. I don't know where Bob got Columbia Gold from, why would a croton be referred to as "gold" when the yellows are only transitional, pre ripening colors.
Unless they were partaking in the Columbian Gold during the naming. At least its not called "Bong Water".
I think the Gold part refers to a better or deluxe version of Columbiana and not so much the color. I guess Super Columbiana would have been a better name.
