I had a bright orange Gerbera planted in front of the Cordyline container, but the leaves got moldy and it never bloomed so I yanked it out. What a sad plant!
I replaced it with one gazania - a $1.00 change.
You can see the kale has bolted in this container (thanks again to Sissy for giving me the proper terminology. She is a wealth of plant information!).
I have since cut down the yellow kale flowers as I did not find them attractive with this planting.
