More Information About Fillers
Like the name says, filler plants are there to fill up space in a container garden. The term "filler" does not do these plants justice though. It would be better to call filler plants "accessories" or "accents" or "visual cement" but unfortunately none of these words rhymes with thriller and spiller and the focus groups did not like the alternative marketing term "presenters-cementers-descenters". Like any accent or accessory, filler plants for container gardening support the main theme of the container garden and highlight the main decorative element, the "thriller".
