Introduction
Imagine a plant that captures the vibrant colors of a tropical sunset and holds them in its leaves all season long. Phasion canna bulbs offer exactly that, bringing a bold, architectural presence to your garden that is hard to match with any other perennial. At Longfield Gardens, we love how these plants transform a standard backyard into a lush, exotic retreat with very little effort.
This guide will walk you through everything you need to know about growing Phasion cannas, from choosing the right spot to overwintering them for next year. Whether you are planting in large garden beds or decorative patio containers, these spring-planted bulbs are designed to impress. By focusing on a few simple needs like sun, water, and warm soil, you can enjoy a season filled with spectacular color.
Why Choose Phasion Canna Bulbs?
Phasion cannas, often recognized by their trade name Tropicanna, are widely considered one of the most beautiful foliage plants in the world. While many garden plants are grown specifically for their flowers, this variety is a "double threat." The leaves themselves are a work of art, featuring wide, pinstriped bands of burgundy, lime green, gold, and bright pink.
When the sunlight shines through the translucent leaves, they appear to glow from within. This makes them a fantastic choice for areas where you can view them from different angles throughout the day. In mid-to-late summer, the plant produces tall stems topped with clusters of brilliant, tangerine-orange flowers. These blooms are highly attractive to hummingbirds and butterflies, adding movement and life to your outdoor space.
Phasion cannas are also remarkably resilient. They grow quickly, often reaching heights of five to six feet in a single season. This fast growth rate makes them ideal for creating temporary privacy screens or adding height to the back of a flower border. They are also naturally resistant to deer, which is a significant advantage for many home gardeners.
Understanding Canna Rhizomes
When you order Phasion cannas, you won't receive a round, onion-like bulb. Instead, you will receive a rhizome. A rhizome is a thick, fleshy underground stem that stores energy for the plant. If you have ever seen a piece of ginger root in the grocery store, you know exactly what a canna rhizome looks like.
These rhizomes are the engine of the plant. Each one contains "eyes" or growth points where the new shoots will emerge. When we ship these to you, we ensure they are firm and healthy, ready to sprout as soon as the conditions are right.
Because cannas are tropical plants, the rhizomes are sensitive to freezing temperatures. In warm climates (USDA zones 7 or 8 through 11), they can stay in the ground year-round. In cooler northern climates, they are treated as annuals or dug up in the fall and stored indoors. This versatility allows gardeners in almost any part of the country to enjoy their tropical beauty.
The Right Plant in the Right Place
Success with Phasion canna bulbs starts with choosing the best possible location. Because these plants grow so large and produce such intense colors, they have high energy requirements.
Sunlight Requirements
To get the most vivid colors in the foliage and the best flower production, plant your cannas in full sun. In gardening terms, "full sun" means at least six to eight hours of direct sunlight every day. If they are planted in too much shade, the colors in the leaves may appear dull or lean more toward solid green, and the stems may become "leggy" as they stretch toward the light.
Soil and Drainage
Cannas are unique because they are very thirsty plants that can actually handle "wet feet" better than most other bulbs. However, for the best growth, they prefer rich, loamy soil that holds moisture but still offers decent drainage. Drainage refers to how quickly water moves through the soil. If you have heavy clay soil, adding some compost or organic matter can help create the perfect environment.
Space to Grow
Given their potential height and width, these plants need room to breathe. A single Phasion canna can spread two to three feet wide. If you are planting a row of them to create a screen, space the rhizomes about 18 to 24 inches apart. This gives each plant enough space to develop its massive leaves without competing too much with its neighbors.
Key Takeaway: Choose the sunniest spot in your garden with rich soil to ensure your cannas reach their full height and display their most vibrant leaf patterns.
When to Plant Phasion Cannas
Timing is the most important factor when planting cannas. Because they are tropical, they have no tolerance for frost and will not grow in cold soil.
Wait until the danger of frost has completely passed in your area. A good rule of thumb is to wait until the soil temperature reaches at least 60°F. If you plant the rhizomes while the soil is still cold and damp, they may sit dormant for a long time or, in extreme cases, struggle to get started.
In northern states, this usually means planting in late May or early June. If you want to get a head start on the season, you can "start" your cannas indoors in pots about four to six weeks before the last frost. Place the pots in a warm, sunny window or under grow lights, and then move the established plants into the garden once the weather is consistently warm.
How to Plant Phasion Canna Bulbs Step-by-Step
Planting cannas is a straightforward process that yields big rewards. Follow these steps to get your rhizomes off to a great start:
- Prepare the Soil: Dig a hole about 4 to 6 inches deep. If your soil is very hard, loosen it a bit deeper to make it easier for the roots to expand.
- Place the Rhizome: Lay the rhizome horizontally in the hole. You may see small bumps or white "eyes" on the surface; try to point these upward, but don't worry too much if you can't tell which way is up. The plant will naturally find its way to the light.
- Cover and Firm: Fill the hole with soil and gently press down with your hands to remove any large air pockets.
- Water Well: Give the area a deep watering immediately after planting to settle the soil around the rhizome.
- Label Your Spot: Since it can take a few weeks for the first shoots to break through the surface, use a garden marker so you don't accidentally dig them up or plant something else on top of them.
What to do next:
- Check the soil every few days to ensure it stays moist but not soggy.
- Watch for the first pointed shoots to emerge—this is the most exciting part!
- Keep the area free of weeds so the young canna doesn't have to compete for nutrients.
Container Gardening with Phasion Cannas
If you have a small yard, a balcony, or simply want to brighten up your patio, Phasion cannas are spectacular in containers. They are the ultimate "thriller" plant for large pots.
When choosing a container, go big. A pot that is at least 12 to 15 inches in diameter is necessary for a single rhizome. If you want to create a mixed arrangement with other plants, use an even larger whiskey-barrel-sized container. Make sure the pot has at least one drainage hole in the bottom.
Use a high-quality potting mix rather than garden soil. Potting mix is lighter and designed to provide the right balance of air and moisture for roots in a confined space. Since pots dry out faster than the ground, you will need to water your container-grown cannas more frequently—sometimes every day during the peak of summer.
Pair Phasion cannas with trailing plants like sweet potato vine or calibrachoa. The dark purple or lime green leaves of a sweet potato vine look incredible draped over the side of a pot, contrasting with the upright, multi-colored leaves of the canna.
Caring for Your Cannas Through the Season
Once your cannas are established and growing, they are relatively low-maintenance. However, a little extra attention will keep them looking their best until the first frost.
Watering Deeply
Cannas love water. While many garden plants prefer to dry out between waterings, cannas do best when the soil is consistently moist. During hot, dry spells, give them a deep soaking once or twice a week. If the edges of the leaves start to look crispy or brown, it’s usually a sign that the plant needs more water.
Feeding Your Plants
Because they grow so much foliage in a short amount of time, cannas are "heavy feeders." This means they use up nutrients in the soil quickly. Applying a balanced, slow-release fertilizer in early summer can help fuel that growth. Alternatively, you can use a water-soluble fertilizer every few weeks. Always follow the instructions on the product label for the best results.
Deadheading for More Blooms
To keep the plant focused on producing new flowers rather than seeds, practice "deadheading." This simply means cutting off the flower stalks once the orange blooms have faded. Snip the stalk back to where it meets the next leaf. This encourages the plant to send up new flower spikes and keeps the garden looking tidy.
Grooming the Foliage
Occasionally, an older leaf at the bottom of the plant may turn yellow or brown. This is a natural part of the plant’s growth cycle. Simply snip these off at the base to keep the plant looking fresh and vibrant.
Key Takeaway: Consistent moisture and regular feeding are the two "easy wins" that will ensure your cannas reach their full, towering potential.
Overwintering Phasion Cannas
If you live in a region where the ground freezes (USDA zones 3-6), your Phasion cannas will not survive the winter outdoors. However, you don't have to buy new ones every year. Saving the rhizomes is a simple process.
Step 1: Wait for Frost
Let the first light frost of autumn hit the plants. You will notice the foliage turn black or brown. This signals the plant to go dormant and move its energy down into the rhizome for the winter.
Step 2: Cut Back
Cut the stalks down to about 4 inches above the ground using a pair of sharp garden shears.
Step 3: Dig and Dry
Carefully dig up the clumps of rhizomes. Use a garden fork rather than a shovel if possible, as this reduces the risk of accidentally cutting the fleshy roots. Shake off the excess soil and let the rhizomes sit in a dry, shaded area (like a garage or porch) for a few days to "cure."
Step 4: Store
Place the rhizomes in a cardboard box or a breathable bag filled with slightly damp peat moss, perlite, or vermiculite. Store the box in a cool, dark, and dry place that stays between 40°F and 50°F. A basement or crawlspace is often perfect. Check them once or twice during the winter; if they look shriveled, mist the packing material with a tiny bit of water.
In the spring, when the weather warms up, you can divide the larger clumps and plant them all over again!
Styling Ideas for Your Landscape
The dramatic look of Phasion canna bulbs makes them a favorite for landscape designers. Here are a few ways to use them effectively:
- The Tropical Border: Plant a row of cannas along a fence or the side of a house. The massive leaves create a wall of color that feels like a private jungle.
- The Poolside Accent: Cannas thrive in the heat and humidity found near water. Their bold orange flowers look stunning reflected in the blue water of a pool or pond.
- The Centerpiece: Use a single canna in the center of a circular flower bed. Surround it with lower-growing plants like lantana, zinnias, or blue salvia to create a tiered look.
- Color Echoing: Play with the colors in the leaves. Plant Phasion cannas near purple-leaved plants (like certain varieties of heuchera) or gold-leaved plants to highlight the pinstripes in the canna foliage.
We have found that at Longfield Gardens, customers often enjoy mixing cannas with other summer-blooming bulbs like dahlias or gladiolus. The broad leaves of the canna provide a perfect backdrop for the intricate flowers of these other varieties.
Simple Troubleshooting
If your cannas aren't performing as expected, the solution is usually found in the basics of sun and water.
- Not Blooming: This is almost always caused by a lack of sunlight. If the plant is in the shade, it will focus all its energy on leaves and skip the flowers. It could also be that the weather has been too cool; cannas need heat to trigger blooming.
- Small Leaves: If the plant stays small, it may be "hungry." Try adding a bit of compost or a liquid fertilizer to give it a boost.
- Holes in Leaves: Canna leaf rollers (small caterpillars) can sometimes be a nuisance. They roll themselves up in the new leaves before they unfurl. You can often simply unroll the leaf and remove the pest by hand, or consult your local extension office for safe treatment options in your area.
Remember, gardening is an evolving process. Every season brings different weather patterns, and the way your plants respond is part of the journey. One of our core goals at Longfield Gardens is to help you navigate these small changes so you can enjoy the rewards of a beautiful yard.

FAQ
Do Phasion canna bulbs need to be dug up every year?
This depends on your location. If you live in USDA zones 7 or 8 through 11, you can leave them in the ground year-round. However, if you live in a colder northern zone (zones 3 through 6), you must dig them up after the first frost and store them in a frost-free place for the winter.
Why are the leaves on my Phasion canna turning green?
The most common reason for faded leaf color is a lack of sunlight. Phasion cannas need at least six hours of direct sun to maintain their intense purple, red, and gold variegation. In shaded areas, the plant produces more chlorophyll to compensate for the lower light, which makes the leaves look greener.
Can I grow Phasion cannas in a pot on my balcony?
Yes, they make excellent container plants. Ensure you use a large pot (at least 12–15 inches wide) with drainage holes and high-quality potting mix. Because containers dry out faster than garden beds, be prepared to water your cannas daily during the heat of the summer.
Are Phasion cannas safe to plant if I have deer in my yard?
While no plant is 100% "deer-proof" if the animals are hungry enough, deer-resistant cannas are generally considered a good choice for gardens where deer pressure is a concern. The thick, fibrous texture of the leaves is not particularly appealing to them, making cannas a great choice for gardens where deer pressure is a concern.
