The Best Tall Plants for Containers
Tall, dramatic plants can turn ordinary planters into works of art. One arresting plant is all you need to fill a container and create visual interest. Virtually any plant can be grown in a container—provided that the container is large enough.
If you garden in a hardiness zone above 6 or 7, you can’t go wrong with a succulent plant as your focal point. Dramatic and very forgiving, if you are a little forgetful about watering. There are many to choose from and striking colors. Even if you live in a cooler climate, you can always grow a succulent as an annual.
A tall amaranth, like ‘Love Lies Bleeding’ (Amaranthus caudatus) or ‘Perfecta’ (Amaranthus tricolor), adds color and drama. These are annual plants, so you will either need to start seed early or buy plants every year. But the nice thing about annuals is that they allow you to experiment and be creative every year.
American arborvitae (Thuja occidentalis)
An evergreen as the centerpiece of a container is elegant, classic, and very low maintenance. Choose one that will hold its shape nicely without a lot of pruning.A good choice would be a conical Arborvitae. Caution, they are deer candy. BUY HERE: https://elevate.ug/product/primidalis/
Bamboo can be a nightmare in the garden, traveling faster than you could possibly keep up. But in a container, bamboo is a conversation piece. Most are hardy enough to survive the winter in their pots.
Big bluestem (Andropogon gerardii)
Grasses may not be quite as invasive as some bamboo plants, but they do spread by runners. Big Bluestem is a lovely 3 season plant made all the lovelier by confining it to a container. If you are mixing it with other plants, make sure it’s a large container, or Big Bluestem will crowd out its neighbors.
Bougainvillea is only hardy in zone 9 and up, but you can either grow it as an annual or bring it indoors for the winter. These are actually vines, not tall plants, so you’ll need to provide some support for it to grow up and around. This will give you another opportunity to be creative.
Boxwood (Buxus sempervirens)
Boxwood can be formal or funky. The real fun of using box is that you can trim it to be anything you want. If you’d like to exercise your creative flair, try a boxwood topiary.
Cabbage tree (Cordyline indivisa)
Cordyline indivisa really does look like a small palm tree and makes an intriguing focal point in a container. It is not hardy below zone 9, but you can bring it indoors as a houseplant, for the winter.
Canna plants add an instant tropical flair, especially the new, colorful varieties. You can buy plants or start the tubers in late winter so that they will be ready to show off, when the weather warms up. Then store the tubers indoors, for next season.
Dracaena plants can grow upwards of 10 ft. tall in containers and there are many to choose from. They are not hardy and would need to be moved indoors for winter. But outdoors they are carefree, even growing in partial shade.
Dwarf Alberta spruce (Picea glauca)
Dwarf Alberta spruce is a gorgeous conical evergreen with dense, bright green needles. It is a bit scratchy, so wear gloves when working around it. Choose a small tree when first planting. The term “dwarf” simply means it is slow growing. With time – a lot of time – it will outgrow you.
Elephant Ear (Alocasia esculenta)
Elephant Ear manages to be both imposing and fun at the same time. There are several new colorful varieties available. However, like cannas, you will either need to buy a plant, which can be expensive, or start your tubers early in the season and then overwinter them indoors.
Feather reed grass (Calamagrostis x acutiflora) ‘Overdam’
Calamagrostis is a cool season grass, which means it is an early riser in the spring and blooms early in the season. After flowering, it remains upright and tall, not floppy or weepy like so many other grasses. So they are perfect for the center of a container.
Fountain grass (Pennisetum setaceum ‘Rubrum’)
Purple fountain grass looks good all season, with its burgundy leaves, spiky purple flowers, and purple-tinged seed pods. It has a wonderful way of swaying in a breeze and adding a rush of sound to your planting. Grasses in containers make wonderful screens, giving you privacy but still allowing you to see through them.
Beautiful pink and purple Fuchsia blossoms
For a container in a shady spot, you can’t do better than a fuchsia. These plants bloom all season long, with no deadheading. Look for an upright variety, if you want it as a center focal point.
Hibiscus look tropical, but most varieties are very hard. They are a multi-branched shrub, but can easily be trained into a tree or standard. Even as a tree, they will be covered in flowers for weeks on end.
New Zealand flax (Phormium tenax)
Phormiums are spiky carefree plants that add a casual look to containers. The leaves will gracefully bend downward, but not enough to cover plants positioned under it. You’ll have a wide variety of colors to choose from, too.
Palm Lily (Cordyline)
Similar to the Cabbage tree, but the palm lily Cordyline is a bit more refined and makes an elegant focal point in a container. you can over-winter it indoors and roll it back out in the spring.
Purple glory tree flowers
If you love the tropical look, Princess flower is a lovely evergreen shrub with stunning purple flowers all season. You will also find it called the Purple Glory Flower. It is only hardy to zone 9, but once again, it makes a nice houseplant.
Sweet Bay (Laurus nobilis)
Bay trees are not just beautiful, they are functional; you can pluck fresh bay leaves right from your container. Bay is slow growing in containers. It will take several years to reach tree size. You can prune it into a topiary or leave it in its natural shrubby shape. It is not hardy, but over-winters well indoors.
