Verbena

The best spilling plants for containers and flower pots are essential to create balance and character in your garden. These spiller plants are not only unique but they add texture and help bring together different aspects of your container garden together.

When designing container gardens, it is a good idea to have variety. This is not only in color, form and size but also in terms of thrillers, fillers and spillers.

Below I’ll explain each of these. And, I’ll have different articles focusing of the kinds of plants in coming articles.

But for now, I’ll keep the focus on spiller or spilling plants.

 

Thrillers vs. Fillers vs. Spillers: What’s the Difference?

So what exactly are thrillers, fillers and spillers?

Well, each of them are a type of plant. Not so much that they’re a species or genus. Instead, they describe the look and function of a group of plants.

 

Thrillers

Thrillers are the main attractions. You can call them the superstars as they’re supposed to be the focal points of your container.

As such, thrillers are often taller, more showy, colorful, dramatic or exotic. Basically, anything that will make people notice. And, to do so, they need to be stunning.

Additionally, they bloom for long periods as well.

 

Fillers

Fillers are the supporting cast just like the supporting actors are in the movie. Their goal is the fill up the space that the thrillers don’t take up.

After all, there’s nothing worse that a vase or pot that’s lacking in contents.

As such, fillers often take up the middle of the pot or are placed around the thrillers.

One of the best things about designing your garden is that there are no rules. It’s really up to you. And, the most important thing is that you’re happy with that you see.

Because of their supporting role, fillers are not as showy or colorful as the thrillers. After all, you don’t want to outshine the main star, right?

 

Spillers

Finally, there are the spillers or spilling plants.

As their name suggests, these are allowed to spill out or cascade from the container. You can use them for tall planters as well as hanging baskets.

The higher up they are, the better the effect.

That said, some pots are lower and closer to the ground. And, spillers are allowed to sprawl across the floor or tabletop.

Because of this, spillers are often trailing plants. At the very least, they have long stems or vines that can overflow and drop over the edges of containers.

That said, some spillers can get “puffy”. Thus, you let them grow and overwhelm the container creating a dropping shape over the pot.

Spillers help soften the look of your container garden.

And, they are positioned near the ends or rims to make it easier for them to grow outwards.

Both flowering and foliage plants work depending on the look you’re going for.
