Introduction

Imagine stepping into your backyard and being greeted by the lush, vibrant energy of a tropical paradise. Canna lilies are the secret to achieving this look, offering bold foliage and brilliant blooms that thrive during the warmest months of the year. Whether you are looking to create a privacy screen of towering leaves or a colorful focal point in a patio container, these plants are remarkably easy to grow and rewarding to witness.

When you decide to buy canna lily bulbs from Longfield Gardens, you are investing in high-quality rhizomes that are ready to hit the ground running. We take pride in selecting varieties that perform well in a wide range of climates, ensuring your summer garden is filled with dramatic textures and vivid colors. This guide will help you understand what to look for when purchasing cannas and how to choose the best varieties for your specific garden goals.

Choosing the right canna lily rhizomes is the first step toward a successful growing season filled with exotic beauty and hummingbird-frequented blooms.

Why Canna Lilies are a Garden Essential

Canna lilies bring an architectural element to the garden that few other plants can match. While many flowers rely solely on their petals for appeal, cannas offer a double feature: stunning flowers and massive, paddle-shaped leaves. This combination makes them a versatile choice for both modern and traditional landscapes.

Tropical Style in Any Climate

You do not need to live in the tropics to enjoy a tropical garden. Cannas are incredibly adaptable. They soak up the summer heat and turn it into rapid growth, often reaching their full height in just a few months. This makes them perfect for northern gardeners who want to add a "vacation vibe" to their yards during the short but intense summer season. In southern regions, they often act as reliable perennials that return year after year with minimal effort.

A Magnet for Pollinators

If you enjoy watching wildlife in your garden, cannas are a fantastic addition. Their bright, tubular flowers are specifically designed to attract hummingbirds. These tiny visitors love the nectar-rich blooms, especially the red, orange, and yellow varieties. Butterflies and bees are also frequent guests, making your garden a lively center for local pollinators.

Low-Maintenance Beauty

One of the biggest draws for busy gardeners is how little maintenance cannas require once they are established. They are not particularly fussy about soil, as long as they get enough water and sunlight. Because they are generally resistant to most common garden pests and diseases, you can spend more time enjoying their beauty and less time troubleshooting problems.

Understanding What You Are Buying: Bulbs vs. Rhizomes

When you search for "canna lily bulbs," you are technically looking for rhizomes. While most gardeners use the term "bulb" as a catch-all for any underground storage organ, cannas grow from thick, fleshy stems that grow horizontally underground.

What is a Rhizome?

A rhizome acts as the plant’s pantry. It stores energy and moisture, allowing the canna to survive dormancy and sprout vigorously when the weather warms up. When you receive your order, you will notice that the rhizome looks a bit like a piece of fresh ginger. It should feel firm and heavy for its size.

The Importance of "Eyes"

When you buy canna lily bulbs, the most important feature to look for is the "eye." Eyes are the small, pointed growth buds from which the new stems will emerge. A healthy rhizome should have at least two to three prominent eyes. More eyes generally mean more stems, which leads to a fuller, more robust plant in its first season. We ensure that the rhizomes we ship are large and have multiple healthy eyes to give you the best possible start.

Key Takeaway: Always look for firm, plump rhizomes with visible growth buds (eyes). These storage organs hold all the energy the plant needs to jumpstart its growth in the spring.

Choosing the Right Size for Your Space

Cannas come in a surprising range of sizes. Knowing the eventual height of the variety you choose is essential for proper placement in your garden.

Giant and Tall Varieties

Tall Cannas are the heavyweights of the summer garden. Some varieties can easily reach 6 to 8 feet in height. These are perfect for:

• Privacy Screens: Plant them in a row along a fence or property line to create a living wall.
• Back-of-Border Placement: Use them as a dramatic backdrop for shorter perennials and annuals.
• Centerpieces: In a large garden bed, a cluster of tall cannas creates a powerful focal point.

Dwarf and Compact Varieties

If you have a smaller yard or prefer gardening in pots, dwarf cannas are an excellent choice. These usually top out at 2 to 3 feet. They offer the same tropical foliage and large flowers but in a much more manageable package. They are ideal for:

• Container Gardening: They fit perfectly in mid-sized pots on a porch or balcony.
• Path Edging: Use them to line a walkway without overwhelming the space.
• Small Beds: They provide the tropical look without shading out nearby plants.

Selecting Foliage and Flower Colors

One of the most exciting parts of shopping for canna lilies is choosing from the diverse array of colors and patterns. The foliage is often just as decorative as the flowers, and in some cases, even more so.

Foliage Options

When you browse our selection, you will see three main categories of foliage:

• Classic Green: Bright, apple-green leaves provide a clean, fresh look that makes flower colors pop.
• Burgundy and Bronze: Deep, chocolatey or purple hues add a sophisticated, moody contrast to the garden. Varieties like Australia are famous for their dark, satiny leaves.
• Variegated: These leaves feature stripes or splashes of color. For example, Bengal Tiger has green and yellow striped leaves.

Phasion (also known as Tropicanna) offers a stunning mix of green, purple, pink, and gold.

Flower Colors

Canna flowers are known for their "saturated" colors. You can find blooms in:

• Fiery Reds and Oranges: These are the traditional favorites and are the most attractive to hummingbirds.
• Cheerful Yellows: Perfect for brightening up a sunny corner.
• Soft Pinks and Creams: These offer a more delicate look for gardeners who prefer a pastel palette.
• Bi-colors: Some flowers feature speckles or contrasting edges, adding even more detail to the display.

When to Buy Canna Lily Bulbs

Timing is everything in gardening. While you can often find cannas in garden centers during the summer, buying them as dormant rhizomes in the spring is the most cost-effective and successful method.

The Benefits of Pre-Ordering

We recommend ordering your cannas early in the year. Many of the most popular and unique varieties sell out quickly. By ordering in late winter or early spring, you secure your favorite colors and sizes before the peak planting rush.

Shipping Based on Your Zone

We time our shipping based on the USDA hardiness zones. See our Shipping Information for details on when your rhizomes arrive in your area—usually about two weeks before the ground is warm enough for them to go outside. This prevents the rhizomes from sitting in a cold mailbox or a hot warehouse for too long.

Starting Early Indoors

If you live in a northern climate with a short growing season, you might want to buy your bulbs early and start them in pots indoors. All About Cannas covers this early-start approach and other basics. Doing this 4 to 6 weeks before the last frost gives the plants a head start. By the time the weather is warm enough to move them outside, you will already have established plants that will bloom much sooner than those planted directly in the ground.

Site Selection: Right Plant, Right Place

To get the most out of your purchase, you need to provide the right environment. Cannas are not difficult to please, but they do have a few "must-haves" for peak performance.

Sunlight Requirements

Cannas are true sun-worshippers. They need full sun to produce their best foliage color and the most flowers. In most regions, this means at least 6 to 8 hours of direct sunlight per day. If they are planted in too much shade, they tend to become "leggy" (tall and weak) and may not bloom at all.

Soil and Drainage

In the wild, cannas often grow near water. This means they love moisture, but they still prefer soil that drains reasonably well. If your soil is heavy clay, adding some compost or organic matter can help improve the texture. They are "heavy feeders," meaning they appreciate rich soil with plenty of nutrients to fuel their rapid growth.

Space to Grow

Because cannas grow so quickly, it is important to give them enough room. When planting, space tall varieties about 2 feet apart. For dwarf varieties, 1 foot of space is usually sufficient. Providing enough airflow between plants helps keep the foliage looking healthy and prevents the spread of any potential issues.

How to Plant Your New Rhizomes

Once your order from Longfield Gardens arrives, planting is a simple process. Follow these steps for the best results:

1. Wait for the Warmth: Do not plant cannas outdoors until the danger of frost has passed and the soil has warmed to at least 60°F.
2. Dig the Hole: Prepare a hole about 4 to 6 inches deep.
3. Position the Rhizome: Place the rhizome in the hole horizontally. Look for the eyes (the growth points) and face them upward. If you cannot tell which side is the top, don't worry—the plant will figure it out and grow toward the light.
4. Cover and Water: Fill the hole with soil and pat it down gently. Water the area thoroughly to settle the soil around the rhizome.

What to Do Next

• Check the soil moisture every few days.
• Avoid overwatering before the first sprouts appear, as the rhizome does not have roots yet to soak up the water.
• Once you see green shoots, increase the frequency of watering.
• Apply a layer of mulch around the base to help hold in moisture.

Water and Fertilizer: The Keys to Success

Cannas are among the thirstiest plants in the summer garden. Because they have such large leaves, they lose moisture quickly through evaporation.

Watering Deeply

Instead of giving your plants a light sprinkle every day, it is better to water them deeply once or twice a week. This encourages the roots to grow deep into the soil. During the hottest parts of the summer, cannas in containers may need water every day. If the leaves start to roll up, it is a sign that the plant is thirsty.

Feeding Your Cannas

Because cannas grow so much biomass in a single season, they need plenty of fuel. Use a balanced, water-soluble fertilizer or a slow-release granular fertilizer throughout the growing season. Following the instructions on the product label will ensure your plants have the nutrients they need to produce those massive leaves and brilliant flowers. If the leaves start to look pale or growth slows down, an extra dose of compost or fertilizer usually does the trick.

Key Takeaway: Think of cannas as "living machines" that convert sun, water, and fertilizer into a tropical display. The more you provide these three elements, the bigger and better the show will be.

Maintaining Your Canna Garden

Cannas are generally very tidy, but a little bit of grooming goes a long way in keeping them looking their best until the first frost.

Deadheading for More Blooms

Deadheading is the process of removing spent flowers. While cannas will eventually drop their old petals, removing the faded flower stalks encourages the plant to put its energy into creating new blooms rather than producing seeds. To deadhead, simply cut the flower stalk back to the next side bud or where it emerges from the foliage.

Managing Foliage

Occasionally, a lower leaf may turn yellow or brown as the plant grows. This is natural. Simply snip off the old leaf at the base of the stem to keep the plant looking fresh. If a windstorm tattered the large leaves, you can trim away the damaged parts without harming the plant.

Pests to Watch For

While cannas are generally hardy, they can occasionally attract "canna leafrollers." These are small caterpillars that roll themselves up in the leaves. If you see leaves that are stuck together or have rows of holes, simply unroll them and remove the pest, or use a garden-safe treatment recommended by your local extension service.

Winter Care: Lifting and Storing

In USDA zones 8 to 11, cannas can usually stay in the ground year-round. However, for those of us in zones 7 and colder, the rhizomes will not survive a freezing winter in the soil. Fortunately, saving them for next year is an easy process.

When to Dig

Wait until the first frost blackens the foliage. This signal tells the plant to go dormant. Cut the stems down to about 2 to 3 inches above the ground.

The Lifting Process

Carefully use a garden fork to lift the rhizomes out of the soil. Be gentle to avoid bruising or cutting the fleshy stems. Shake off the excess dirt, but you do not need to wash them perfectly clean.

Storing for Spring

1. Dry Them Out: Let the rhizomes air dry in a frost-free area (like a garage) for a few days.
2. Pack Them Away: Place the rhizomes in a box or breathable bag filled with slightly damp peat moss, vermiculite, or sawdust. This keeps them from drying out completely without causing rot.
3. Find a Cool Spot: Store the box in a cool, dark place that stays between 40°F and 50°F. An unheated basement or a crawl space is usually perfect.
4. Check Periodically: Once or twice during the winter, check on your rhizomes. If they look shriveled, mist them lightly with water. If any spots look soft or mushy, remove those pieces to keep the rest healthy.

Designing with Canna Lilies

When you buy canna lily bulbs, think about how their unique shape will interact with other plants in your yard. Their bold texture provides a perfect "anchor" for a variety of garden styles.

The Mediterranean Look

Pair cannas with other sun-lovers like hibiscus, lavender, and ornamental grasses. The contrast between the broad canna leaves and the fine texture of grasses creates a sophisticated, layered look.

The Lush Jungle Garden

For a high-impact tropical feel, plant cannas alongside elephant ears (Colocasia), dahlias, and caladiums. This combination focuses on "maximalism," using different leaf shapes and colors to create a dense, exotic environment.

Using Cannas as a Screen

If you have an unsightly AC unit or a neighbor's fence you'd like to hide, tall varieties like 'Red King Humbert' or 'Musifolia' are your best friends. Within a few months, they will create a thick, colorful screen that provides privacy and beauty at the same time.

Container Styling

In pots, use the "Thriller, Filler, Spiller" method. A dwarf canna makes the perfect "Thriller" (the tall, central focal point). Surround it with "Fillers" like lantana or petunias, and add a "Spiller" like sweet potato vine to trail over the edges. Because cannas and sweet potato vines both love heat and water, they make excellent companions.

FAQ

When is the best time to buy canna lily bulbs?

The best time to buy is in late winter or early spring. Ordering early ensures you get the best selection of varieties before they sell out. We ship the rhizomes at the appropriate planting time for your specific USDA hardiness zone so they arrive ready for the garden.

Are canna lilies actual bulbs?

While they are often called bulbs, they are technically rhizomes. These are thick, horizontal underground stems that store the plant's energy. When you buy them, they will look like firm, fleshy roots rather than the rounded shape of a tulip or onion bulb.

Can I grow canna lilies in containers?

Yes, cannas are excellent for containers. For the best results, choose dwarf or compact varieties that reach 2 to 3 feet in height. Ensure your pot has drainage holes and use a high-quality potting mix, as container-grown cannas will need more frequent watering and fertilizing than those in the ground.

Do I need to dig up my canna lily bulbs every year?

This depends on where you live. In USDA zones 8 to 11, cannas are perennials and can stay in the ground all year. In zones 7 and colder, the ground freezes deep enough to kill the rhizomes, so you should lift them in the fall and store them in a cool, frost-free place for the winter.
