You’re sold on container gardening. You’ve picked out a pot, filled it with quality potting mix, and now you’re wondering what to plant. That’s a personal choice, of course, but here’s an old rule of thumb to help you out: Use three different types of plants -- a thriller, a filler, and a spiller.
The thriller is the look-at-me showboat plant. That role is fulfilled in this planter by ‘Purple Haze’ canna, which stands out with its height, purple-tinted leaves, and tropical-looking orange flowers.
It’s joined by a multicolor calibrachoa performing the role of both filler and spiller -- filling in around the base of the canna and spilling over the sides of the container. Calibrachoa, also known as Million Bells, will continue to bloom even after the canna flowers are gone.
In this container, orange mums play the role of filler around purple fountaingrass. They’re so thick with color that there’s no need (or room) to add a spiller plant.
Finally, we have this container, which features a burgundy coleus as the thriller and pink petunias as both filler and spiller. The gray-green dusty miller is an accent -- a welcome touch of the unexpected.
