corrplot one column multiple groups single plot

I would like a corrplot, where I only have the first column. I got that solution from here: Corrplot with only one variable on x axis

library(corrplot) 
corrplot(cor(iris[,1:4])[1:4,1, drop=FALSE], cl.pos='n')

but I would like the first column to repeat WITHIN THE SAME PLOT by group:

I am not married to using corrplot but need some similar solution. Thanks for any and all help.

Here is a hacky way to do it without an additional package:

library(corrplot)
Dat<-cor(iris[,1:4])[1:4,1, drop=FALSE]
PlotDat<-cbind(Dat,Dat,Dat)
corrplot(PlotDat, cl.pos='n')
