Purchase an end cap, fill with rock, soil, and plant. You can put these in the center of a very large pot to stabilize, and add amazing height and color to a container that has trailing plants (no end cap or rock needed if you are placing in a container)
Good to know for next year Provide drainage while keeping large pots light: Cut dollar store pool noodles and use as drainage material instead of stones. Large planters will be light enough to move later if needed.
