Introduction

Imagine stepping out into your backyard and being greeted by towering, paddle-shaped leaves in shades of emerald, bronze, and deep burgundy. Canna lilies bring a bold, tropical energy to any landscape, offering vibrant blooms that last from midsummer until the first frost. At Longfield Gardens, we love how these easy-to-grow canna lilies transform a standard flower bed into an exotic retreat with very little effort.

This guide is designed for home gardeners who want to know the best time to secure these "bulbs"—which are technically called rhizomes—to ensure a season full of color. We will cover the ideal window for pre-ordering, how shipping schedules align with your local weather, and what to look for when making your selection. Whether you are a beginner or a seasoned gardener, understanding the timing of your purchase is the first step toward a successful growing season.

The best time to buy canna bulbs is in late winter to early spring to ensure you get the best selection of varieties before they sell out.

The Best Window for Purchasing Canna Bulbs

The search for the perfect garden begins long before the soil warms up. For cannas, the most important rule is that early shoppers get the best selection. While you won't be planting these heat-loving plants in the frozen ground of January or February, that is exactly when the most popular varieties become available for purchase online.

Most gardeners find that the ideal time to buy canna bulbs is between January and March. During these months, we offer our full inventory, including the most sought-after Tall Cannas, stunning variegated foliage types, and compact dwarf cannas that are perfect for containers. By placing your order during this window, you "lock in" your favorites before they are marked as sold out.

Buying early also allows you to plan your garden layout with certainty. Knowing exactly which colors and heights you have coming helps you choose the right companion plants, like dahlias or caladiums, to create a cohesive look. While it might feel strange to shop for summer flowers while there is still snow on the ground, this proactive approach is a hallmark of successful gardening.

Key Takeaway: Secure your canna rhizomes in late winter or very early spring. This ensures you have access to the widest range of colors and leaf patterns before the spring rush begins.

Why Pre-Ordering Beats Last-Minute Shopping

You might be tempted to wait until the weather turns warm to look for cannas at a local garden center. However, pre-ordering online offers several distinct advantages for the home gardener.

First, the selection online is significantly broader than what you will find in a brick-and-mortar store. Local shops often carry only a few standard red or yellow varieties. If you are looking for something specific—like a canna with striped Tropicanna style leaves or a delicate pink bloom—pre-ordering is often your only way to guarantee you’ll find it.

Second, pre-ordering ensures that the rhizomes are handled and stored in professional, climate-controlled environments until it is time for them to travel to you. At Longfield Gardens, we keep our stock in peak condition, ensuring that when they arrive at your door, they are firm, healthy, and ready to grow.

Finally, pre-ordering takes the guesswork out of the calendar. Instead of having to remember to go to the store at exactly the right moment, your order is placed in a queue and scheduled to ship according to your specific climate. This allows you to focus on other spring tasks, knowing your cannas will arrive exactly when you need them.

Understanding Shipping Cycles and Your USDA Zone

Timing your purchase is one thing, but timing the delivery is another. To make gardening as simple as possible, we coordinate our shipping schedule with the USDA Hardiness Zone Map. These zones are a standard guide that helps gardeners understand which plants will thrive in their local climate based on average annual minimum winter temperatures.

When you buy canna bulbs early in the year, we do not ship them immediately if your area is still experiencing freezing temperatures. Because cannas are tropical plants, their rhizomes can be damaged by extreme cold during transit. Instead, we hold your order in our temperature-controlled facility in Lakewood, New Jersey.

We typically begin shipping in the spring, starting with the warmest southern zones and moving north as the weather settles. Our goal is to have your bulbs arrive about two weeks before the ideal planting time for your specific area. This gives you a small window to prepare your garden beds or gather your pots without the bulbs sitting in a box for too long.

• Warm Zones (8-10): Shipping usually begins in early to mid-March.
• Transition Zones (6-7): Shipping typically occurs in April.
• Cooler Zones (3-5): Shipping usually happens in late April or May.

Remember that these dates can shift slightly based on the year’s weather patterns. If an unexpected cold snap or a late-season blizzard is forecasted, we may delay shipping briefly to ensure your plants arrive in prime condition.

When to Buy if You Plan to Start Indoors

If you live in a region with a short growing season, you may want to buy your canna bulbs even earlier so you can start cannas indoors. Cannas love heat and can be a bit slow to sprout in the cool soil of early spring. By starting them in pots inside your home or a greenhouse, you can get a four-to-six-week head start on the blooming season.

If this is your plan, you should aim to have your bulbs in hand by late February or March. When you buy during the peak pre-order season, you can request an early ship date if your local weather allows for safe transit.

Starting indoors is a simple process:

1. Place the rhizomes in pots with quality potting soil.
2. Keep the soil lightly moist and place the pots in a warm, sunny spot.
3. Once the danger of frost has passed and the soil outside is warm, you can transplant your established plants directly into the garden.

By the time your neighbors are just putting their bulbs in the ground, your pre-started cannas will already have several inches of lush foliage, leading to earlier flowers and a more dramatic display.

Selecting the Right Varieties During Your Purchase

When you are browsing during the buying season, it helps to know which canna types fit your space. Because they grow so quickly, choosing the right variety at the time of purchase prevents the need for moving plants later.

Tall Varieties

Standard cannas can reach heights of 4 to 6 feet (and sometimes taller!). These are perfect for the back of a flower border or for creating a living privacy screen around a patio or pool. When buying these, look for Tall Cannas known for their vigorous growth and large flower heads.

Dwarf Varieties

If you have a smaller garden or prefer container gardening, dwarf cannas are an excellent choice. These typically stay between 2 and 3 feet tall but still offer the same oversized tropical leaves and bright flowers. They are much easier to manage in pots and won't tip over in the wind as easily as the taller types.

Foliage-Focused Cannas

While the flowers are stunning, many gardeners buy cannas specifically for their leaves. Some varieties feature chocolate-bronze foliage, while others have tiger-striped variegation in yellow, orange, and green. If foliage is your priority, make sure to read the descriptions carefully during your spring shopping to find the most colorful leaf patterns.

What to do next:

• Identify your USDA Hardiness Zone to understand your shipping window.
• Decide if you want tall varieties for a screen or dwarf types for containers.
• Browse the available colors and leaf patterns in late winter to secure your favorites.
• Prepare a warm, sunny spot in your yard that receives at least 6 hours of sunlight, or read How to Grow Summer Bulbs in Containers if you are planting in pots.

Buying for Success: Quality Over Price

When you are deciding when and where to buy, it is important to consider the quality of the rhizomes. In the gardening world, you often get what you pay for. Very inexpensive bulbs found at big-box clearance bins later in the season may be dehydrated or have been stored improperly.

Healthy canna rhizomes should feel firm to the touch, similar to a fresh ginger root. They should have visible "eyes" or growth points—these are the small bumps where the new stems will emerge. At Longfield Gardens, we work with trusted growers to ensure our cannas are true to variety and arrive in prime condition. We stand behind our 100% guarantee, meaning if there is an issue with the condition of your delivery, we are here to help.

Investing in high-quality stock during the primary buying season ensures that your plants have the energy they need to grow rapidly. A healthy rhizome will establish roots quickly and produce more flowers throughout the summer than a stressed or undersized bulb.

What to Do After Your Canna Bulbs Arrive

Once you have timed your purchase and your bulbs have arrived, the final step is ensuring they stay healthy until they go into the ground. Even if you bought them at the perfect time, how you handle them in those first few days matters.

First, open the box immediately. It is important to let the rhizomes breathe. Remove any plastic packaging and check the bulbs to ensure they are firm. If you aren't ready to plant them yet because the soil is still too cool, you can store them in a cool, dry, dark place—like a basement or a closet—where temperatures stay between 45°F and 55°F.

If your bulbs arrive and you see small sprouts already starting, this is a sign of a healthy, eager plant! In this case, it is best to pot them up in some lightly moistened soil and keep them in a bright window until the outdoor temperatures are consistently warm.

Simple Rules for Timing Your Canna Garden

Gardening is most rewarding when we work with nature’s timeline rather than against it. To keep your canna experience simple and successful, follow these three basic rules for timing:

1. Buy for Variety, Not for Weather: Purchase your bulbs based on when the inventory is best (January–March), not based on when the sun is shining outside.
2. Wait for the Soil: Do not be in a rush to put cannas in the ground. They are tropical plants that thrive when the soil temperature is at least 60°F. A good rule of thumb is to plant them around the same time you would plant tomatoes.
3. Watch the Frost: Ensure the danger of spring frost has completely passed before moving any indoor-started cannas outside. These plants have tender leaves that do not like the cold.

By following this timeline, you avoid the frustration of "missing out" on a favorite color and the disappointment of planting too early in cold soil.

Summary of Buying and Planting Milestones

To help you visualize the year, here is a quick breakdown of the canna calendar for most US gardeners:

• January – February: The best time to browse online and place your pre-order to ensure the best selection.
• March – April: This is when most orders are shipped. If you want an early start, this is the time to begin potting rhizomes indoors.
• May – June: Once the soil is warm and the nights are mild, it is time to plant your cannas outdoors.
• July – September: Enjoy the peak blooming season! This is when your early planning pays off with massive tropical displays.
• October – November: In colder zones, this is when you would dig up your rhizomes to store them for next year. In warmer zones (8-10), you can simply mulch them and leave them in the ground.

Why Canna Lilies are Worth the Wait

While it takes a little bit of planning to buy and plant cannas at the right time, the reward is well worth the effort. There are very few other plants that can provide so much height, texture, and color in a single growing season. They are the "workhorses" of the summer garden, standing up to heat and humidity when other flowers might begin to wilt.

Cannas are also incredibly versatile. They look just as home in a formal garden bed as they do in a whimsical, cottage-style garden or a modern poolside container. Because they are so easy to care for once they get started, the most "difficult" part of growing them is simply choosing which of the beautiful varieties you want to buy.

"The secret to a spectacular canna display isn't a special fertilizer or a complicated trick; it is simply getting the timing right—from the moment you click 'purchase' to the day the first sprout breaks the soil."

FAQ

Can I buy canna bulbs in the fall to plant the following year?

It is generally best to buy canna bulbs in the late winter or spring. While some retailers may sell them in the fall, most canna rhizomes are harvested in autumn and need a period of dormancy. Buying fresh stock in the spring ensures the rhizomes haven't dried out during improper winter storage and are ready to grow immediately.

What should I do if my canna bulbs arrive and it is still snowing?

If your bulbs arrive while the weather is still wintry, do not worry. Open the box to let them breathe and store them in a cool, dry, dark place like a basement. Alternatively, you can plant them in pots indoors to give them a head start, as long as you have a warm, sunny window for them.

Is it better to buy canna seeds or rhizomes?

Buying rhizomes (bulbs) is much more effective for home gardeners. Canna seeds have very hard shells and can be difficult to germinate, often taking a long time to reach blooming size. Rhizomes are established pieces of the plant that contain plenty of stored energy, allowing them to grow quickly and bloom in their very first season.

How do I know if I am buying a tall or a dwarf canna?

When shopping at Longfield Gardens, we clearly label each variety with its expected mature height. Tall varieties generally reach 4 to 6 feet, while dwarf varieties stay between 2 and 3 feet. Always check the product description during your purchase to ensure the variety fits your specific garden space.
