At Longfield Gardens, we believe that every yard deserves a touch of the tropics. Canna lilies are among the most rewarding summer bulbs because they grow quickly and bloom reliably until the first frost. These plants are tough, heat-tolerant, and exceptionally easy to care for once you understand a few basics in All About Cannas.
In this guide, we will explore the best red varieties, how to plant them for success, and how to keep them thriving all summer long. From soil preparation to winter storage, you will find everything you need to enjoy these stunning blooms year after year. Red cannas are more than just a flower; they are a surefire way to bring high-impact color and vertical interest to your outdoor space.
Why Red Cannas Are a Garden Game-Changer
Red is a powerful color in the garden. It draws the eye and creates a focal point that stands out against green foliage and blue skies. While cannas come in many shades, the Red and Burgundy Spring Planted Bulbs offer a specific kind of intensity that can transform a dull corner into a vibrant oasis.
One of the best things about cannas is their versatility. They are just as happy in a large flower bed as they are in a decorative container. Because they grow tall, they provide a vertical element that many other summer-blooming plants lack. They can act as a backdrop for shorter perennials or stand alone as a structural centerpiece.
Beyond their beauty, red cannas are famous for attracting hummingbirds and butterflies. The tubular shape of the flowers and the bright color act like a beacon for pollinators. If you enjoy watching wildlife in your yard, planting red cannas is an easy way to invite these welcome guests.
Understanding Canna Lily Bulbs
When you shop for canna lily bulbs, you are actually purchasing "rhizomes." A rhizome is a thick, fleshy underground stem that stores energy for the plant. While most people call them bulbs, knowing they are rhizomes helps you understand how they grow.
These rhizomes spread horizontally under the soil. As they grow, they send up new shoots, which is why canna clumps become thicker and more impressive each year. When you receive your rhizomes from us, they will likely look like lumpy, brown roots. Don't let their humble appearance fool you; inside is all the energy needed to produce a massive, flowering plant.
The size of the rhizome often correlates with the vigor of the plant in its first season. We take pride in providing high-quality, healthy rhizomes that are ready to take off as soon as the weather warms up.
Popular Varieties of Red Canna Lilies
There are several varieties of red canna lilies, each with its own unique personality. Some are prized for their flowers, while others are grown specifically for their dark, moody foliage. Choosing the right one depends on your space and your personal style.
Canna 'The President'
This is the classic red canna lily. It features large, brilliant scarlet-red flowers that sit atop bright green foliage. 'The President' is a mid-sized variety, usually reaching about 3 to 4 feet in height. It is a reliable bloomer and looks wonderful when planted in large groups. If you want a traditional, clean look, this is the variety for you.
Canna 'Red King Humbert'
For those who want double the drama, 'Red King Humbert' is an excellent choice. This variety is famous for its dark, bronze-to-maroon foliage and deep red flowers. The contrast between the dark leaves and the fiery blooms is breathtaking. It is a taller variety, often reaching 5 to 6 feet, making it perfect for the back of a border or as a living privacy screen.
Canna 'Cannova Red'
If you have a smaller garden or prefer container gardening, the Cannova series is a great option. These cannas are bred to stay more compact, usually topping out at 2 to 3 feet. 'Cannova Red' offers the same tropical look as its larger cousins but fits perfectly in a pot on your balcony or porch. They also tend to start blooming earlier in the season than taller varieties.
Canna 'Lucifer'
While technically a bicolor, 'Lucifer' is often grouped with red cannas because of its intense red petals. Each petal is edged in a bright yellow border, creating a flaming effect. It is a dwarf variety that works well at the front of a garden bed or in mixed containers.
Key Takeaway: Choose 'The President' for classic red-on-green contrast, 'Red King Humbert' for dark foliage and height, or 'Cannova Red' for smaller spaces and pots.
The Best Spot for Red Canna Lily Bulbs
Getting the location right is the most important step in growing healthy cannas. These are tropical plants, so they have a few specific preferences that will help them reach their full potential.
Sunshine is Non-Negotiable
To get those iconic red blooms, cannas need plenty of sunlight. They should be planted in a spot that receives at least 6 to 8 hours of direct sun each day. In cooler climates, full sun is essential. If you live in an extremely hot region, a little afternoon shade can help prevent the leaves from scorching, but too much shade will result in fewer flowers and leggy growth.
Soil and Drainage
Cannas are not too picky about soil type, but they do best in soil that is rich in organic matter. They also appreciate good drainage. While they enjoy moisture, they don't want to sit in stagnant water, which can cause the rhizomes to rot.
If you have heavy clay soil, you can improve it by adding compost or well-rotted manure before planting. This helps loosen the soil and adds the nutrients that these "heavy feeders" need to grow quickly.
Space to Breathe
Because cannas can grow quite large, they need enough room for air to circulate around them. This helps prevent fungal issues like rust or leaf spot. When planning your garden, think about the mature width of the variety you have chosen. Most red cannas need about 1 to 2 feet of space between each plant.
How to Plant Red Canna Lily Bulbs
Planting canna rhizomes is a simple process that anyone can do. The key is to wait until the right time and get the planting depth right.
Timing Beats Tricks
Cannas are very sensitive to cold. Do not plant them outside until the danger of frost has passed and the soil has warmed up to at least 60°F. In many parts of the US, this is usually in late May or early June. If you're ordering rhizomes, check our Shipping Information page for zone-based timing.
If you want a head start, you can plant your rhizomes in pots indoors about 4 to 6 weeks before the last frost. Keep them in a warm, sunny spot, and then transplant them into the garden once the weather is consistently warm. This is a great way to enjoy blooms earlier in the summer.
Step-by-Step Planting
- Prepare the Soil: Dig a hole or loosen the soil in your planting area to a depth of about 6 inches.
- Position the Rhizome: Lay the rhizome horizontally in the hole. You might see small "eyes" or buds on the rhizome; these should be facing upward. If you can't tell which way is up, don't worry—the plant will find its way.
- Depth and Spacing: Cover the rhizome with 2 to 4 inches of soil. Space multiple rhizomes about 12 to 24 inches apart, depending on the variety's mature size.
- Water In: Give the area a good drink of water to settle the soil around the rhizome.
What to Do Next
- Mark the spot with a garden stake so you don't accidentally dig it up before it sprouts.
- Be patient; cannas can take a few weeks to show their first leaves, especially if the soil is still warming up.
- Check the soil moisture every few days, keeping it consistently damp but not soggy.
Caring for Your Cannas Throughout the Summer
Once your red cannas are established, they are remarkably low-maintenance. However, a little bit of attention will go a long way in ensuring they bloom continuously.
Water Correctly, Not Constantly
Cannas are thirsty plants. Because they have large leaves, they lose moisture quickly through evaporation. During the heat of the summer, they may need to be watered several times a week.
Instead of a light sprinkle every day, give them a deep soaking. This encourages the roots to grow deeper into the soil, making the plant more resilient. If you are growing cannas in pots, they will dry out much faster than those in the ground, so check them daily.
Feeding Your Plants
Because cannas grow so much in a single season, they require plenty of fuel. We recommend using a balanced, water-soluble fertilizer every few weeks during the growing season. Alternatively, you can apply a slow-release fertilizer at planting time. Look for a fertilizer with a slightly higher middle number (phosphorus) to encourage more blooms.
Deadheading and Grooming
To keep your plants looking their best, remove the spent flower stalks. This process, called deadheading, prevents the plant from putting energy into seed production and encourages it to produce more flowers. Simply cut the flower stalk back to the next set of leaves or where a new bud is forming.
You should also remove any tattered or yellowing leaves throughout the season. This keeps the plant looking tidy and helps prevent pests from moving in.
Growing Red Cannas in Containers
If you don't have a lot of garden space, or if you want to decorate your deck, red cannas are excellent container plants. They add height and drama to mixed "thriller, filler, spiller" arrangements.
Choosing the Right Pot
For standard red cannas like 'The President', you will need a large, heavy pot. A container that is at least 15 to 18 inches in diameter is a good starting point. Smaller varieties like 'Cannova Red' can live happily in a 12-inch pot.
Make sure your container has drainage holes. Cannas like water, but they don't like to swim. A heavy pot (like ceramic or stone) is also a good idea because tall cannas can become top-heavy and might blow over in a strong wind.
Potting Mix
Use a high-quality, well-draining potting soil. Avoid using garden soil in pots, as it is too heavy and won't drain properly. You can mix in a little compost to give the plants an extra boost of nutrients.
Container Care
Plants in containers need more frequent watering and fertilizing than those in the ground. In the peak of summer, you may need to water your potted cannas every morning. Fertilize every two weeks to keep the foliage lush and the flowers coming.
Key Takeaway: When growing in pots, use a large, heavy container with drainage holes and water deeply every day during hot weather.
Saving Your Red Canna Bulbs for Next Year
In USDA hardiness zones 8 and warmer, cannas can usually stay in the ground all year. However, if you live in zone 7 or colder, the winter temperatures will kill the rhizomes if they are left outside. The good news is that lifting and storing them is very simple.
When to Dig
Wait until the first light frost kills the foliage. The leaves will turn brown or black, which is a signal that the plant has finished its work for the year. Don't worry—the cold that kills the leaves won't hurt the rhizomes immediately, as the soil protects them. However, you must dig them up before the ground actually freezes.
Steps for Storage
- Cut Back: Use garden shears to cut the stalks down to about 2 or 3 inches above the ground.
- Dig Carefully: Use a shovel or garden fork to lift the clumps of rhizomes out of the soil. Start digging a few inches away from the stems to avoid cutting into the fleshy roots.
- Clean and Dry: Shake off the excess soil. You can rinse them gently with a hose if they are very muddy. Let them sit in a dry, shady spot (like a garage or shed) for a few days to "cure." This dries out the outer skin and helps prevent rot.
- Pack Them Up: Place the rhizomes in a cardboard box or a paper bag. Cover them with slightly damp peat moss, vermiculite, or even shredded newspaper. This keeps them from drying out completely without making them soggy.
- Store: Keep the box in a cool, dark place where the temperature stays between 40°F and 50°F. An unheated basement or a crawl space is usually perfect.
Checking During Winter
Once a month, take a quick look at your stored rhizomes. If they look shriveled, mist them lightly with a spray bottle. If you see any soft or moldy spots, cut those sections away and discard them to keep the rest of the clump healthy.
Designing with Red Canna Lilies
Red cannas are a designer's secret weapon. Their bold color can be used in many ways to enhance your garden's aesthetic.
The Tropical Look
Pair red cannas with other large-leafed plants like elephant ears or bananas. Add bright orange and yellow flowers nearby to create a "hot" color palette that feels like a Caribbean vacation.
The Modern Look
For a more contemporary feel, plant a single variety in a row. A line of 'Red King Humbert' cannas against a modern fence or a minimalist wall looks architectural and sophisticated. The dark foliage of some red varieties is particularly striking in modern designs.
Color Combinations
Red is a versatile color that works with many different partners:
- Red and Chartreuse: Pair red cannas with lime-green plants like 'Marguerite' sweet potato vine or coleus. The bright green makes the red pop.
- Red and Blue: For a high-contrast look, plant red cannas near blue salvias or agapanthus.
- Red and Bronze: Using plants with bronze or burgundy foliage (like certain heucheras or fountain grasses) creates a rich, moody landscape that looks incredible in the late afternoon sun.
Simple Troubleshooting Tips
Even though cannas are easy, you might run into a few common questions. Here is how to handle them the simple way.
My Cannas Aren't Blooming
The most common reason for a lack of flowers is not enough sun. If your plants are in a shady spot, they will focus on growing leaves rather than blooms. Another reason could be a lack of nutrients. Try a fertilizer with higher phosphorus to give them a nudge.
The Leaves Have Holes
If you see small holes or "scrolls" on the leaves, you might have canna leaf rollers. These are small caterpillars that roll themselves up in the leaves. The easiest way to deal with them is to simply unroll the leaf and remove the caterpillar by hand, or trim off the affected leaf and dispose of it.
The Edges of the Leaves are Brown
This is often called "leaf scorch." It usually happens during periods of extreme heat and low humidity. It can also happen if the soil dries out too much. To fix this, increase your watering and consider adding a layer of mulch around the base of the plant to hold in moisture.
Conclusion
Red cannas are a fantastic investment for any gardener looking to add height, drama, and vibrant color to their yard. Whether you choose the classic green leaves of 'The President' or the dark, sophisticated foliage of 'Red King Humbert', you are sure to enjoy the tropical energy they bring. Remember that success comes down to a few basics: plenty of sun, consistent water, and a little bit of food.

FAQ
Can I leave my red cannas in the ground all winter?
This depends entirely on your USDA hardiness zone. If you live in zone 8 or warmer, your cannas can usually stay in the ground year-round with a layer of mulch for protection. If you live in zone 7 or colder, you will need to dig up the rhizomes after the first frost and store them indoors to keep them safe from freezing.
How many red canna bulbs should I plant together?
For a full, lush look, we recommend planting cannas in groups of three or more. Space the rhizomes about 12 to 18 inches apart. This allows them enough room to spread while creating a dense clump of foliage and flowers that makes a much bigger impact than a single plant standing alone.
Why are the leaves on my red cannas turning yellow?
Yellowing leaves can be caused by a few different factors. The most common is poor drainage or overwatering, which can lead to root issues. If the soil is very wet, let it dry out a bit. Yellowing can also be a sign that the plant needs more fertilizer. Check that your plant is getting enough sunlight and that the soil isn't staying soggy.
Do red cannas attract pests like deer or rabbits?
Generally, cannas are considered deer and rabbit resistant. The thick, fibrous texture of the leaves is not very appealing to most foraging animals. While no plant is 100% "animal-proof," cannas are a much safer bet than many other summer flowers if you have wildlife frequently visiting your garden.
