Have you heard the planting adage "Thiller, Filler, Spiller"? That is a handy way to remember that when you plant a container, it is good to have a central, taller, flashy plant (your "Thriller"), surrounded by some smaller plants that will fill up the open space, and perhaps add some interesting foliage (your "Filler), and cap things off with something that will have a cascading effect over the sides of the container (the "Spiller").
When I was at my local plant nursery out here in the middle of nowhere, the woman who was helping me select some plants clearly thought I was a nut case when I babbled my Thriller, Filler, Spiller credo. The little nursery is actually pretty good, particularly if you go there on the days that that plants are delivered from the wholesaler. And obviously the staff is fairly tolerant of ditzy locals. I had fun shopping for some plants and even managed to get my containers planted before I came down with this wretched virus that is tormenting me this week.
