10 Thrillers, Fillers, and Spillers For Stunning Container Displays

Containers give us the freedom and creativity to arrange plants around color schemes and themes. They attract pollinators while enchanting the garden with dynamic color and interest across multiple seasons. Join gardener Katherine Rowe in reviewing winning plant selections that thrill, fill, and spill for gorgeous pots and containers.

It’s easy to achieve captivating container displays by incorporating “thriller,” “filler,” and “spiller” plants. There are no rules for building gorgeous potted arrangements, but winning plant combinations help get the creativity flowing.

“Thriller” plants are central features that bring intrigue, drama, and interest. They become focal points, draw the eye, and anchor the arrangement.

The “filler” plants support the main attraction with big visual interest through color and form. They round out the display and add cohesion.

“Spiller” plants soften edges and add vertical interest. They often sport varying textures, fine-leaved and delicate or lush and broad, to highlight the display.

Container recipes vary as widely as garden style, but following the thriller-filler-spiller combination streamlines successful designs. Consider the combination’s color scheme and factor in texture and growth habits. Pair contrasting colors for impact or similar hues for an easy blend. Vary bloom and foliage color and shapes. Most of all, have fun with the freedom to play and arrange delicious selections.

Thrillers

The flowering containers, including cascading purple calibrachoa, Asystasia gangetica 'Variegata', and purple fountain grass, create a striking display with their vibrant purple hues and varied leaf textures.
Thrillers create stunning focal points in container arrangements.

Built to thrill, container focal points become the heart of the arrangement. Whether standing alone or among unified fillers and spillers, the thrillers become the primary plant for designing the planter. Depending on the balance and layout of your scheme, place them anywhere in the arrangement: in the middle, off-center, or in the back. Use their color and leaf textures to guide other plant choices.

Mandevilla

Mandevilla is a tropical vine with large, trumpet-shaped flowers in shades of red, and white, and glossy, dark green leaves.
Showy mandevilla captivates with vibrant blooms and glossy foliage.

You can’t help but notice showy mandevilla, with attractive glossy foliage, standing tall in a container design. Trumpet blooms in red, pink, yellow, and white stand out among rich green leaves on vining stems.

Plants benefit from support like a trellis, obelisk, or arbor. For selections with bushier growth that don’t need support, look for mandevilla’s close relative, Diplodenia. Diplodenia has a fountain of arching foliage and the same tubular flowers in a more compact form.

Mandevilla resists heat, drought, and disease and adapts to various light conditions. It overwinters indoors where not hardy in bright, indirect light.

Pentas

Pentas lanceolata features clusters of small, star-shaped flowers in vibrant lilac color, with narrow, pointed green leaves.
Thrilling blooms delight gardeners and pollinators with vibrant colors.
