I do not know how I missed this thread.
I do not know if I should laugh or cry.
SummerMan - if you have not found enough suggestions to satisfy you then shame on you.
Sorry but you are beyond picky.
Your containers are limited in size so that limits you selection.
This thread is too long for me to read every post so forgive me if this question has been answered. Do your containers have good drainage? I am not talking about rock in the bottom of the container. I am talking about holes in the sides and bottom. If you do not have good drainage then plant fake plants. Real plants will not survive.
DITTO Applestar and RBG. Incorporate culinary herbs and vegetables.
I did not read all of the posts but I did see some comments about Royal Purple. Purple is neither masculine or feminine. True Royal Purple is called Royal Purple because it is the most costly color to create. In times past only Royalty could afford Royal Purple. Hence the name "Royal Purple."
The color referred to as Purple in our time is actually Auborgine. A lovely color but not quiet the depth of color of Royal Purple.
SummerMan I apologies for sounding strident.
I would love to see your finished product.
