Quick-growing plants for container gardens
Story and Photos by Courtney Keck
I’m sure you’ve heard the terms filler, thriller, and spiller when it comes to container gardens. A filler fills the space, a thriller draws the eye, and a spiller balances out the other two. In combination, they make for very attractive displays.
Container gardens are an easy way to add excitement to an otherwise simple space. Permanence not being a factor, they also allow for change when you get tired of the same plants. Now that it’s time to plant container gardens, you may be wondering about plants that could fill a container quickly, provided a little tender loving care is included. Here are some to think about.
Dichondra ‘Silver Falls’ is an annual that can fill up a container in weeks. It’s also a great plant to tolerate heat and drought, and does not like moist soil – understandable once you learn that it’s native to the desert regions of Texas, New Mexico, and Arizona. It will tolerate some shade. It can be used solitarily or in combination with other plants.
Sedum ‘Lemon Ball’ might fill your fancy, as well. Just like the name implies, it has a chartreuse lemon color that surely stands out. Just like ‘Silver Falls’ dichondra, it needs little water. By the way, don’t confuse little water with no water at all. You’re sure to disqualify it from the fast fillers category because it won’t grow rapidly without needed water. It looks great in a container by itself, with other plants, or in the garden. If you want it to survive the winter, plant it in the ground in a sunny location on the south side of the house.
If you like grasses, try using ruby grass (Melinis nerviglumis) as a fast filler in a container. It boasts beautiful pink plumes that turn white as they mature. It’s a moderate water user that does best in a sunny location.
My next fast filler is blanket flower (Gaillardia x grandiflora). The flowers come in various hues of red and yellow, depending on the cultivar. It prefers full sun and does not tolerate wet feet. If you’re looking to attract pollinators to the landscape, this is a plant to achieve that goal.
Yarrow (Achillea spp.), Gerbera daisy (Gerbera jamesonii), dusty miller (Senecio cineraria), and Sedum all qualify as fast fillers in containers. Some of these are good substitutions for the mundane selection of container plants. Yarrow species are perennial plants that require full sun and do not tolerate wet feet. You may place them in an area that doesn’t get as much sun, but you will be left wishing for more flowers. They come in an array of flower colors from pink to red to yellow, and even white. They’re also good plants for pollinators. Gerbera daisy blooms are large, as you may know. These come in a variety of colors, such as orange, yellow, white, red, and pink. They do prefer moist soil, but do not tolerate wet feet (few plants do tolerate wet feet). Dusty miller is a perennial plant, although it’s often used as an annual bedding plant. It is prized for its attractive silvery foliage. It can handle full sun or partial sun, and likes moist soil. As for sedums, there are many different kinds to choose from. They are great for those that forget to water occasionally, or may neglect their plantings. They’re succulents, so do not need a lot of watering. They also come in different hues of green from bluish to reddish to yellowish. If you’re lucky, your sedum will flower for you, providing added interest.
