The difference between a container planting that looks finished and one that looks like it’s still waiting for something is almost always leakage. Thrillers and fillers get most of the attention, but neither creates density on its own. That makes a spiller. Spills run over the edges of the containers, making them look purposeful, rich and complete.
Choosing the right spiller installation means that it matches the conditions of the container and the surrounding plants. Thriller, filler, plays with ideas they are plentiful. Especially for the role of spiller, what matters is lateral spread and rapid density—something that quickly fills negative space and spills limply to the edges of the container without sniffing its neighbors.
Let’s dive in and learn about the best spills to enhance the look of your containers.

Partial shade and consistently moist soil is what it likes. In colder zones it often overwinters in the container rather than needing an annual replacement, which many annuals can’t manage. A find Jenny creepers at Garden Goods Direct (and they’re on sale for Memorial Day!)
