What are Thriller, Filler, and Spiller Plants?
The thriller, filler, and spiller concept is a tried-and-true formula for designing eye-catching container gardens. It’s all about creating a harmonious balance of height, fullness, and cascading elements within a single planter.
Here’s a breakdown of each component:
Thrillers: The Stars of the Show
Thrillers are the attention-grabbers, the divas of your container garden. These vertical beauties add height, drama, and a focal point to your arrangement. They can be flowering plants that steal the spotlight with their vibrant blooms, or they can be foliage plants with striking colors or textures that demand to be noticed. Think towering Dracaena, stately Cordyline, or regal Canna lilies.
Fillers: The Supporting Cast
While thrillers may be the stars, fillers are the unsung heroes that bring fullness and substance to your container garden. These mounded or rounded plants fill in the gaps, creating a lush and bountiful display. Fillers can be flowering or foliage plants, but their primary role is to complement the thriller and provide a sense of cohesion. Imagine the perfect backdrop of petunias, geraniums, or coleus surrounding your thriller.
Spillers: The Cascading Beauties
Last but not least, spillers are the trailing plants that soften the edges of your container and add a whimsical, cascading effect. These delicate beauties drape over the sides of your planter, creating a sense of movement and drawing the eye downward. Spillers can be flowering vines, such as million bells or trailing petunias, or foliage plants, like sweet potato vines or ivy.
Choosing the Perfect Combination
Now that you understand the roles of thriller, filler, and spiller plants, it’s time to choose the perfect combination for your container garden. Here are a few factors to consider:
Considering Light Requirements
Before selecting your plants, take note of the light conditions in your desired location. Some plants thrive in full sun, while others prefer partial shade or even full shade. Matching your plants’ light requirements is crucial for their health and longevity.
Complementary Colors and Textures
When selecting your thriller, filler, and spiller plants, consider their colors and textures. For a harmonious look, choose plants with complementary hues or contrasting textures that create visual interest. Depending on your personal style, you can also opt for a monochromatic color scheme or a mix of warm and cool tones.

Designing Your Container Garden Masterpiece
With your plants selected, it’s time to bring your vision to life. Here are some tips for creating a stunning container garden masterpiece:
Selecting the Right Container
Choose a container that complements the style and size of your plants. Consider the material (terracotta, plastic, or ceramic), color, and drainage capabilities. Ensure the container is large enough to accommodate the root systems of your thriller, filler, and spiller plants.
Arranging the Plants
When arranging your plants, place the thriller in the center or at the back, depending on the desired viewing angle. Surround the thriller with the fillers, creating a mounded or rounded shape. Finally, add the spillers along the edges, allowing them to cascade over the sides of the container.

Maintenance and Care Tips
Regular maintenance is key to keeping your container garden looking its best. Water your plants consistently, being careful not to overwater or drown them. Fertilize regularly with a balanced, water-soluble fertilizer to provide the necessary nutrients. Deadhead spent blooms to encourage continued flowering, and prune as needed to maintain the desired shape and fullness.
Frequently Asked Questions
Absolutely! Mixing different types of plants, such as annuals, perennials, and even small shrubs or vegetables, can create a unique and diverse container garden. Just be mindful of their light, water, and nutrient requirements, and choose plants with compatible needs.
The watering frequency will depend on factors like the size of your container, the plant types, and the weather conditions. As a general rule, check the soil moisture daily and water when the top inch or two of soil feels dry. Adjust as needed during hot or dry periods.
Regular pruning and deadheading are essential to maintain the desired shape and fullness of your container garden. Remove spent blooms, trim back leggy growth, and thin out overcrowded areas to keep your plants looking their best.
Many annuals and tender perennials won’t survive the winter in containers. However, you can overwinter hardy perennials, shrubs, and some bulbs by moving the containers to a protected area, such as an unheated garage, shed, or covered porch. Before bringing them indoors, cut back any dead or dying foliage and stop watering and fertilizing. Check on them periodically throughout the winter and water sparingly if the soil becomes completely dry. In early spring, you can gradually reintroduce them to outdoor conditions and resume regular care.
For a low-maintenance container garden, choose drought-tolerant plants like succulents, herbs, or native species that require less frequent watering. Opt for self-cleaning plants that don’t need deadheading, and use slow-release fertilizers to reduce the need for frequent feeding.

Unleashing your green thumb has never been more rewarding than with the thriller, filler, and spiller technique. By combining height, fullness, and cascading elements, you can create a stunning container garden that’s not only a feast for the eyes but also a relaxing retreat in your outdoor space.
