The Canna plant or the Canna lily is another of the Lily plant varieties that can easily brighten up any space. Scientifically referred to as the Canna, this plant is a member of the Cannaceae plant family, native to Central America, Mexico, West Indies, South and Southeastern America.
A tropical plant, the Canna lily is mostly known for its beautiful Canna flowers. The plant also has some long wide leaves, much like those of the banana plants.

What Do Canna Flowers Look Like
The Canna lily flowers are a rather beautiful sight. The various Canna lily varieties produce Canna flowers in different colours such as cream, orange, pink, red, white, yellow, etc. These flowers are rather flashy and shaped somewhat like paddles. These Canna flowers generally bloom from the late spring season and until the early summer season.
An important trick to encourage blooms in the Canna lily plant is to deadhead Canna lily flowers once they start to fade away. This deadheading is essential to make way for a new batch of flowers to bloom.
Canna Lily Seeds/ Canna Lily Bulbs
Even though Canna lily seeds can be used to grow a Canna plant, it is not the most common way of growing the plant. Instead, the Canna lily bulbs are a more popular way of growing the Canna lily plant. However, Even though these structures are referred to as bulbs, aren’t true bulbs, but are rhizomes.
Unlike the true bulbs, rhizomes are more like fattened extensions of the stalks of the Canna lily plant. These rhizomes encourage the spread of the Canna lily plant from beneath the soil as they are known to multiply. Rhizomes are an easier way to grow a Canna lily plant.
How to Plant Canna Bulbs/ Rhizomes
One can easily use a container to sow the Canna lily bulbs. Just fill the container with some good quality potting mix and insert the Canna lily bulbs 4 to 6 inches deep in the soil. There must be a gap of around 18 to 24 inches between each two consecutive lily bulbs that get planted in the soil. Planting them in such a system allows the Canna plant quite some space to grow.
The soil in which the plant is growing should be a good quality well-draining soil. The inclusion of organic matter in the soil mix further helps to boost the growth of the Canna lily plant. For best results, the soil chosen should be slightly acidic, maintaining a pH level of around 6 to 6.5.
Replanting Canna Bulbs/ Rhizomes
The Canna rhizomes need to be replanted once they start sprouting leaves. This sprouting of the leaves is an indication that the bulb has developed a sturdy root system.
Here is a guide to how you can replant the Canna bulbs.
- Start with choosing an appropriate container for the plant. An appropriate container measures just around 16 inches in diameter and has enough drainage holes to flush out the excess water from the soil.
- In the previous container, loosen the soil and gently pull out the already-sprouting Canna lily bulb from the previous container.
- Layer the bottom of the new planter with some gravel and pebbles to further boost the drainage of the excess water.
- Then, fill around one-third of the new planter with some good quality and well-draining potting soil. You can also add some compost to aid in the fertilization of the plant.
- Gently lower the plant into the pot, and layer it with some more potting soil, ensuring that the roots of the plant are completely covered.
- Water the plant and move it to a desired spot in the house.
Canna Plant Care
The Canna lily plant loves the full sun. It can also very well survive in partially-shaded regions. But the leaves and the Canna lily flowers tend to grow better and at a faster face when exposed to the bright sunlight.
The watering needs of the plant are a little extra, in comparison to other general houseplants but it can very well be adhered to. The Canna lily requires watering around once or twice a week as the plant prefers its soil to maintain a moist consistency. However, refrain from turning the soil soggy as it can lead to root rot.
Average temperature levels must be maintained to favour the growth of Canna lilies. The plant cannot survive too much of a cold temperature. The ideal temperature range for growing a Canna lily is around 50 to 90 degrees Fahrenheit. Under no circumstance should the plant be exposed to a temperature below 40 degrees Fahrenheit.
It is also essential to maintain warm and humid conditions for the healthy growth of the plant as it is native to tropical regions. However, if you live in a drier region, you can take to regularly misting the plant. Another trick to increase humidity is to place a tray filled with water below the Canna lily pot, ensuring that the water is not in contact with the bottom of the planter.
When it comes to fertilizing Canna lilies, keep in mind that they are rather heavy feeders. An ideal fertilizer for the Canna lily is rich in organic matter. This means that even compost can be used as a fertilizer for the plant. During the growing period of the plant, that is the spring and summer seasons, the Canna lily plant should be fertilized around once a month. Fertilization should be completely avoided during the winter season.
The Canna lily is not very winter hardy. Thus, as winter approaches, the Canna lily plants should be shifted inside the house. If shifting is not possible, the Canna lily rhizomes of the plant should carefully be extracted, after cutting back the plant to the ground, and stored in a location that maintains a temperature above 40 degrees Fahrenheit until the winters come to an end. These stored rhizomes should be occasionally sprayed with water to prevent them from drying off, but they should also not be consistently kept on a dampened surface as well.
