Orange cannas are remarkably easy to grow and reward even the most casual gardener with months of spectacular color.
Why Choose Orange Canna Lily Bulbs?
Orange is one of the most energetic colors in the garden. It stands out in the bright midday sun and seems to glow during the "golden hour" just before sunset. Choosing orange canna lily bulbs allows you to play with a variety of garden designs. Orange flowers look stunning when paired with deep purple salvias, bright yellow marigolds, or even dark, moody foliage plants.
Beyond the flowers, cannas are loved for their leaves. Some orange-flowering varieties feature bright green foliage that looks fresh and crisp. Others offer bronze or burgundy leaves that provide a sophisticated, dark backdrop for the fiery blooms. This combination of flower and foliage makes them a "two-for-one" plant for visual impact.
Orange cannas are also fantastic for attracting wildlife. The tubular flowers are a favorite for hummingbirds and butterflies. Watching a hummingbird hover near a tall stalk of orange cannas is one of the great rewards of the summer season. Because they bloom from mid-summer until the first frost, they provide a long-lasting food source for these welcome garden visitors.
Selecting the Right Orange Varieties
When you start looking for orange canna lily bulbs, you will find several distinct types. It is helpful to understand the differences in height and foliage color before you make your selection. This ensures you pick a plant that fits your space and your personal style.
Classic Tall Varieties
Tall cannas can reach heights of 4 to 6 feet. These are perfect for the back of a flower border or for creating a temporary privacy screen. 'Wyoming' is one of the most famous orange varieties. It features massive, dark bronze-purple leaves and large, ruffled orange flowers. The contrast between the dark foliage and the bright petals is truly striking.
Compact or Dwarf Varieties
If you have a smaller garden or want to grow cannas in pots, compact cannas are the way to go. Varieties like 'Orange Punch' usually stay around 3 or 4 feet tall. They offer all the tropical beauty of their taller cousins but in a more manageable size. These are excellent for the middle of a flower bed where they won't overshadow other plants.
Variegated Foliage Options
Some orange cannas offer extra interest with striped or variegated leaves. 'South Africa' is a popular choice that features green leaves with yellow veins and bright orange flowers. ‘Stuttgart’ canna is another unique variety known for its green and white variegated leaves and delicate peach-orange blooms. These varieties add a layer of texture that looks great even when the plant is not in flower.
What to do next: Look at the space where you want to plant. If you need height, choose 'Wyoming.' If you are planting in a container, look for a compact variety like 'Orange Punch.'
Understanding Canna Rhizomes
While many people call them "bulbs," cannas actually grow from rhizomes. A rhizome is a thick, fleshy underground stem that stores energy for the plant. When you receive your orange canna lily bulbs, you will notice they look a bit like ginger roots.
Each rhizome will have several "eyes" or growth points. These are the small bumps or sprouts where the new stems will emerge. A healthy rhizome should feel firm and heavy for its size. If you see small sprouts already starting, do not worry. This is a sign that the plant is ready to grow.
At Longfield Gardens, we ensure our rhizomes are true to variety and arrive in prime condition for planting. We ship our plants at the right time for your specific USDA hardiness zone. This means your order will arrive when the weather in your area is getting close to the ideal window for planting.
The Best Time to Plant
Timing is everything when it comes to cannas. These are tropical plants that love warmth. They are very sensitive to cold soil and frosty air. The most important rule for canna success is to wait for the right temperature.
Checking Soil Temperature
You should wait to plant your rhizomes until the soil has warmed to at least 60°F. In most regions, this happens a few weeks after the last frost date in the spring. If you plant them too early in cold, wet soil, the rhizomes may sit dormant or struggle to get started.
Starting Indoors
If you have a short growing season, you can give your cannas a head start. About 4 to 6 weeks before the last frost, plant the rhizomes in pots indoors. Place the pots in a warm, sunny window or under grow lights. By the time the weather warms up outside, you will have established plants ready to go into the garden. This often results in earlier blooms. For more detail, see this guide to starting canna lily bulbs indoors.
Hardiness Zones
In USDA zones 7 and warmer, cannas can often stay in the ground all year. In zones 6 and colder, they are treated as annuals or dug up and stored for the winter. Checking your hardiness zone helps you decide whether you will need to lift the rhizomes in the fall.
Choosing the Perfect Location
To get the most out of your orange canna lily bulbs, you need to find a spot that meets their basic needs. Cannas are not demanding, but they do have a few "must-haves" for peak performance.
Sunlight is Key
Cannas are sun worshippers. For the best flowers and the strongest stems, they need full sun. This means at least 6 to 8 hours of direct sunlight every day. If they are planted in too much shade, the plants will become "leggy" as they stretch for light, and they will produce fewer flowers.
Soil and Drainage
While cannas love water, they also need soil that drains well. They do not like to sit in stagnant, soggy mud. "Drainage" simply refers to how fast water leaves the soil after a rain. If you have heavy clay soil, you can improve it by mixing in some compost or well-rotted manure. This creates a looser structure that cannas love.
Protection from Wind
Tall canna varieties have large leaves that can act like sails in a storm. If you live in a very windy area, try to plant your cannas near a fence, a wall, or a group of sturdy shrubs. This provides a bit of a windbreak and helps prevent the leaves from shredding or the tall flower stalks from leaning.
How to Plant Orange Canna Lily Bulbs
Planting cannas is a straightforward process. Once you have your spot picked out and the soil is warm, follow these simple steps for the best results.
- Prepare the Soil: Loosen the soil to a depth of about 8 to 10 inches. This makes it easy for the new roots to spread out and find nutrients.
- Dig the Hole: Dig a shallow hole about 3 to 4 inches deep.
- Position the Rhizome: Lay the rhizome in the hole horizontally. It does not matter which way the "eyes" are pointing, as the plant will naturally find its way toward the light. However, if you see obvious sprouts, pointing them upward can give them a slightly faster start.
- Spacing: Space your orange canna lily bulbs about 12 to 18 inches apart. They need plenty of room to grow, as each rhizome will produce multiple stems and the clumps will widen over the summer.
- Cover and Water: Fill the hole with soil and press down gently with your hands. Water the area thoroughly right after planting. This settles the soil around the rhizome and "wakes up" the plant.
Key Takeaway: Plant your rhizomes 3 to 4 inches deep and 12 to 18 inches apart in a sunny spot once the soil is warm.
Summer Care and Maintenance
Once your cannas start growing, they are very self-sufficient. However, a few simple care tasks will keep them looking their best from July until October.
Watering Correctly
Cannas are thirsty plants. Because they have such large leaves, they lose a lot of moisture through evaporation. During the heat of the summer, they may need water several times a week. The goal is to keep the soil consistently moist but not swampy. If the edges of the leaves start to turn brown and crispy, it is often a sign that the plant needs more water.
Feeding Your Plants
Because cannas grow so fast and produce so much foliage, they are "heavy feeders." This means they use up nutrients in the soil quickly. Applying a balanced, all-purpose fertilizer once a month during the growing season will encourage more blooms and taller growth. You can also mulch around the base of the plants with compost to provide a steady supply of nutrients.
Deadheading
"Deadheading" is the practice of removing faded flowers. On a canna, the flower stalks produce multiple clusters of blooms. Once a cluster has finished blooming, you can snip it off. This keeps the plant looking tidy and prevents it from putting energy into making seeds. Once the entire flower stalk has finished blooming, you can cut it back to where it meets the foliage.
Growing Cannas in Containers
Orange canna lily bulbs are fantastic candidates for container gardening. They add instant height and drama to a patio or entryway. Growing in pots also allows you to move the plants around to catch the best sunlight.
Picking the Right Pot
Cannas have large root systems, so you need a large container. A pot that holds at least 5 to 10 gallons of soil is usually sufficient for one large rhizome. Ensure the pot has plenty of drainage holes at the bottom so excess water can escape.
Using High-Quality Potting Mix
Do not use garden soil in your containers. It is too heavy and can pack down, preventing air and water from reaching the roots. Instead, use a high-quality potting mix. These mixes are designed to be lightweight and provide the perfect balance of moisture retention and drainage.
Watering Container Cannas
Plants in pots dry out much faster than those in the ground. In the peak of summer, you might need to water your container cannas every day. A quick check with your finger can tell you if the soil is dry. If the top inch feels dry to the touch, it is time to water. For additional guidance, read how to plant canna lily bulbs in pots.
Overwintering Your Canna Rhizomes
In most of the United States, winters are too cold for cannas to survive in the ground. If you want to grow the same orange cannas next year, you will need to "lift" and store the rhizomes.
When to Dig
Wait until the first light frost kills the foliage. The leaves will turn black or brown, which is a sign that the plant has gone dormant. Cut the stems down to about 2 or 3 inches above the ground.
Digging and Cleaning
Carefully use a garden fork or shovel to lift the clump of rhizomes out of the soil. Be careful not to bruise or cut the fleshy roots. Shake off the excess soil. You do not need to wash them; leaving a little bit of dry soil on them is actually fine.
Storage Conditions
Let the rhizomes dry in a shady, frost-free area for a few days. This is called "curing." Once they are dry to the touch, place them in a cardboard box or a plastic bin with some ventilation holes. Pack them in slightly damp peat moss, vermiculite, or sawdust.
Store the box in a cool, dark place where the temperature stays between 40°F and 50°F. A basement or an insulated crawl space is often perfect. Check on them once or twice during the winter. If the rhizomes look shriveled, mist the packing material with a little water. If any look soft or molded, remove them immediately.
What to do next: Mark your calendar for the first frost. Having your storage boxes and peat moss ready ahead of time makes the cleanup process much easier.
Common Questions and Simple Fixes
Gardening is a learning process, and sometimes things don't go exactly as planned. If your orange cannas aren't performing quite like you expected, the solution is usually very simple.
Why Are There No Flowers?
The most common reason for a lack of blooms is not enough sunlight. If your cannas are in a shaded spot, try moving them to a sunnier location next year. Another reason can be a lack of nutrients. If the soil is poor, the plant will focus on leaves instead of flowers. A bit of fertilizer can often fix this.
Why Are the Leaves Tattered?
If your canna leaves have holes or look shredded, it could be a few things. Wind is a frequent culprit, as the large leaves tear easily. Sometimes, slugs or caterpillars may snack on the young leaves before they unfurl. Usually, the plant is strong enough to outgrow this minor damage. You can pick off any visible pests by hand or use a simple organic slug bait if necessary.
When Will They Bloom?
Cannas generally start blooming about 60 to 90 days after planting. If you planted them in late May, you should see flowers by late July or early August. Once they start, they will keep producing new flower stalks until the weather turns cold.
Designing with Orange Cannas
Orange is a versatile color that can set many different moods in your garden. Think about the other plants you enjoy and how orange cannas might complement them.
- The Tropical Look: Pair orange cannas with large-leafed plants like Elephant Ears (Colocasia) or ornamental bananas. The different textures of the leaves create a lush, jungle-like feel.
- The Sunset Border: Combine orange cannas with yellow black-eyed Susans and red dahlias. This warm color palette looks incredible in the late afternoon sun.
- High Contrast: Use blue or purple companion plants. The complementary nature of orange and blue makes both colors appear more vivid. Blue salvia or purple heart (Tradescantia) are excellent choices.
No matter your design style, these plants bring a sense of joy and abundance. Their height and color make them the "exclamation point" of the summer garden.

FAQ
Can I leave my orange canna lily bulbs in the ground all winter?
This depends on your USDA hardiness zone. If you live in zone 7 or warmer, cannas can usually survive the winter in the ground if you apply a thick layer of mulch. In zone 6 or colder, the ground freezes deep enough to kill the rhizomes, so you must dig them up and store them indoors.
How deep should I plant orange canna lily bulbs?
You should plant canna rhizomes about 3 to 4 inches deep. This depth provides enough soil cover to keep the rhizome moist and cool while allowing the new sprouts to reach the surface easily. If you plant them too deep, they may be slow to emerge.
Do orange cannas need a lot of fertilizer?
Yes, cannas are considered heavy feeders because they grow so much foliage and many flowers in a single season. We recommend using a balanced, all-purpose fertilizer once a month starting about a month after planting. This ensures the plant has the energy it needs to bloom continuously until frost.
Why are the leaves on my orange canna lily turning yellow?
Yellowing leaves can be a sign of a few different things, but the most common is a lack of water or nutrients. If the soil is very dry, the plant cannot take up the minerals it needs. Ensure you are watering deeply and consistently, and consider adding a bit of fertilizer to boost the plant's health.
