What Is the "Thriller, Filler, Spiller" Formula?
The "Thriller, Filler, Spiller" formula is the secret to creating balanced, eye-catching container gardens. Here’s what each component means:
Thriller:
The star of the show! Thrillers are tall, bold, and dramatic plants that grab attention. Think of them as the centerpiece of your container.
Filler:
These are medium-height plants that fill in the space around your thriller. They add volume, texture, and complementary colors.
Spiller:
Trailing plants that cascade over the edges of the container, softening the overall look and adding movement.
When you combine these three types of plants, you create a container that’s full, dynamic, and beautifully balanced.
Why the "Thriller, Filler, Spiller" Formula Works
This method works because it creates visual interest and balance. The thriller draws the eye, the fillers add density, and the spillers soften the edges. It’s a foolproof way to make any container garden look professional, even if you’re a total beginner.
How to Plant a "Thriller, Filler, Spiller" Container
Here’s a simple diagram to guide you:
Example of using the thriller, filler, spiller method in a container.
Start with the Thriller: Place it in the center of the pot if the container will be viewed from all sides. If the container will sit against a wall, position the thriller toward the back.
Add the Fillers: Plant your fillers around the thriller. These should create a cushion of foliage and flowers that blend with the thriller.
Finish with the Spillers: Place your spillers around the edges of the container so they can trail down.
Water and Fertilize: Use quality potting mix and water thoroughly after planting. Add a slow-release fertilizer for healthy growth.

Tips for Beginner Gardeners
Pick Plants with Similar Needs: Make sure all the plants in your container have similar sunlight and water requirements. For example, pair sun-loving petunias with drought-tolerant sweet potato vine.
Use the Right Potting Mix: Avoid garden soil in containers. Use a high-quality potting mix for better drainage and root health.
Don’t Overcrowd: Leave some space between plants for growth. Your container will look fuller as the plants mature.
Water Wisely: Check your container daily, especially in warm weather. Containers dry out faster than garden beds.
Experiment!: Don’t be afraid to mix and match colors, textures, and heights. Gardening is all about trying new things.
