How to Design Beautiful Containers
One of the simplest ways to make your home feel welcoming in spring is with a well-designed container. The difference between a pot that feels intentional and one that feels chaotic usually comes down to structure & Color.
My go-to framework for container design is thriller, filler, spiller. It’s simple, flexible, and works whether you’re planting one pot or ten.
Start With Structure: Thriller, Filler, Spiller
If you’re only using three plants, each one should play a clear role:
- Thriller: the bold, vertical anchor
- Filler: the plant that fills out the body of the container
- Spiller: the element that softens the edge and flows over the rim
This balance keeps your container from feeling flat or overcrowded.
My Favorite Thrillers
Thrillers set the tone for the entire container. They should be confident, vertical, and visually strong.
Some of my favorites include:
- Salvia
- Suncredible sunflowers
- Truffula Pink gomphrena
- Perennials like a small tree, shrub or evergreen
Choose one strong thriller (or a grouping of several of the same) rather than multiple different tall plants competing for attention.
Here is the gomphrena (thriller) with coral jade sedum (spiller) & pansies (filler)
Fillers: Where Most of the Color Lives
Fillers provide fullness and most of the color. They should be generous and suited to your light conditions.
I regularly use:
- Geraniums
- Coleus
- Begonias
- Vinca
- Pansies (especially for early spring or cooler, shadier areas)
Light conditions matter more here than anywhere else. A plant that thrives in sun will always struggle in shade, no matter how good it looked at the garden center.
Reminder that you will need to provide some fertilization once late spring hits and the plants have eaten through what was available at planting.
Here is an example of how I learned over the years. Early spring (Late March & early April) is very tough for container options in zone 6a. But, by that time of year I very much want to enjoy my containers. Look at the difference from just planting a filler (pansies) a few years back to adding a thriller of hellebore this year!
Just 1 plant makes a huge difference.
Spillers: The Finishing Touch
Spillers soften the edge of the container and add movement.
My go-to spillers include:
- Lemon Coral sedum
- Silver Falls dichondra
- Proven Winners Vista petunias
- Trailing geraniums
One or two spillers is usually enough to keep the container feeling balanced.
Plan for a Mid-Season Switch
If you want containers to look good from spring through fall, a mid-season refresh is almost always necessary. Cool-season plants fade, summer heat takes over, and even well-designed containers can start to look tired.
Swapping a few key plants keeps containers looking intentional. For winter, I love transitioning containers to simple greens and structural elements for a clean, timeless look.
Or go Perennial for a year round container
If you pick the right perennials, you can have the same container for years. Here I have a large planter with a Christmas tree, hardy sedum, geum, echinecea & cranberry that I could enjoy all year long!
I did need to plant this tree out into the landscape after about 3 years. But, that was years of enjoyment with no maintainence aside from watering and a bit of fertilizer occasionally.
Here is that same container later in the year with the echinecea blooming
Here is a different container that has smokebush, viburnum, goldenrod & mums
And here is the same container year 2
