Are Calla Lillies Invasive
Last Updated on July 8, 2023
Calla lilies are a beautiful and popular flower, but many people don’t know that they can be quite invasive. If you’re thinking about planting calla lilies in your garden, it’s important to be aware of their potential to spread and take over other plants. Calla lilies are rhizomatous, meaning they produce thick underground stems (called rhizomes) that can easily spread beyond the boundaries of your garden bed.
Once established, calla lilies can be difficult to control, so it’s best to err on the side of caution and plant them in containers or areas where they won’t escape.
Calla lilies (Zantedeschia aethiopica) are beautiful, elegant flowers that make a great addition to any garden. However, they can be quite invasive if not kept in check. Calla lilies spread rapidly by rhizomes (underground stems) and can quickly take over an area if left unchecked.
They can also be difficult to remove once established.
If you’re thinking about planting calla lilies in your garden, it’s important to be aware of their potential for invasiveness. Take steps to prevent them from spreading by removing flower heads before they go to seed and keeping the plants well-pruned.
With a little effort, you can enjoy these lovely flowers without worry about them taking over your garden!
Calla Lily
A calla lily is a beautiful flower that has long been associated with elegance and sophistication. The name “calla” comes from the Greek word for beauty, and “lily” refers to the shape of the flower. Calla lilies are native to South Africa, but they have been cultivated all over the world for centuries.
These flowers are most commonly white, but they can also be found in shades of pink, yellow, and orange. Calla lilies typically bloom in late spring or early summer. When choosing calla lilies for your garden, it is important to select a variety that is suited to your climate.
Calla lilies are relatively easy to care for. They prefer full sun but will tolerate partial shade. These flowers are drought-tolerant and do not need a lot of water once they are established.
Calla lilies should be fertilized monthly during the growing season with a balanced fertilizer.
When planting calla lilies, it is important to keep the bulbs cool and moist until ready to plant. They can be planted in either pots or directly in the ground.
Bulbs should be planted about 8 inches deep and 12 inches apart. Once planted, calla lilies will naturalize and spread over time.
Where are Canna Lilies Native to
Cannas are native to tropical and subtropical regions of the world, including parts of Africa, South America, and Central America. In the wild, they can be found growing in damp areas such as marshes and swamps. Cannas are also popular ornamental plants, and their large, showy flowers make them a common sight in gardens around the world.
There are over 50 species of Canna Lily, but only a few are commonly cultivated as ornamentals. The most popular varieties include Canna indica, Canna x generalis (the hybridized form of C. indica and C. glauca), and Canna flaccida. These three varieties come in a wide range of colors, including reds, oranges, yellows, and greens.
Cannas are relatively easy to care for, but they do require some basic knowledge to thrive. They should be planted in soil that is rich in organic matter and kept moist (but not soggy). Full sun is best for optimal growth and flowering; however, cannas will tolerate partial shade if necessary.
Regular fertilization is also important to keep these plants looking their best.
Dormant Calla Lily
A dormant Calla Lily is a lily that has no leaves and is not blooming. The plant will be either brown or yellow in color. When the plant is in this state, it is not actively growing.
However, the plant can still be alive and healthy. Dormancy is a normal part of the Calla Lily’s life cycle and usually occurs during winter months.
There are several reasons why your Calla Lily may go into dormancy.
One reason may be due to changes in temperature or light exposure. If your plant was previously kept indoors and you move it outdoors, it may go into dormancy until it adjusts to its new environment. Another reason for dormancy could be lack of water or nutrients.
Be sure to check your plant’s soil before watering to make sure it actually needs water. Over-watering can also lead to dormancy.
If you think your Calla Lily is going into dormancy, there are some things you can do to help it along.
First, make sure it is getting enough sunlight exposure each day. If possible, move your plant to an area with more light exposure (but not direct sunlight). Second, continue watering your plant regularly and fertilizing it according to package directions.
You may also want to try repotting your lily into fresh potting mix . With proper care, your Calla Lily should come out of dormancy and begin growing again soon!
When to Cut Back Calla Lilies in the Fall
Although they are a summertime favorite, calla lilies (Zantedeschia spp.) can be kept as houseplants or in the garden year-round in many regions. If you live in an area with frost, you’ll need to dig up the bulbs and store them indoors over winter. In warmer climates, calla lilies can be left in the ground and will rebloom year after year.
In late summer or early fall, when the foliage of your calla lilies begins to yellow and die back, it’s time to cut them back. Cut the foliage down to about 6 inches above the ground. Continue to water and fertilize your plants as usual; they will regrow from the base come springtime.
How to Overwinter Calla Lilies in Pots
If you want to overwinter your calla lilies in pots, there are a few things you need to do. First, make sure the pot is big enough. Calla lilies can get quite large, so you’ll need a pot that’s at least 12 inches wide and deep.
Second, fill the pot with well-drained soil. Calla lilies like their roots to be moist but not soggy, so make sure the soil you use drains well.
Third, water your calla lily regularly during the growing season.
Once the weather starts to cool off in fall, reduce watering slightly but don’t let the soil dry out completely. Fourth, bring the pot indoors before the first frost hits. Place it in a bright spot out of direct sunlight and keep an eye on it over winter.
If it looks like it’s starting to go dormant (the leaves will turn yellow and die back), stop watering it altogether until spring when you can start again from scratch.
With a little care, your calla lily should survive winter just fine and be ready to bloom again come spring!

How Do You Keep Calla Lilies from Spreading?
If you’re looking to keep your calla lilies from spreading, there are a few things you can do. First, you can plant them in a pot or container with a drainage hole. This will help to prevent waterlogging and reduce the chances of the bulbs spreading.
Secondly, you can add a layer of gravel or sand to the bottom of the pot before planting. This will also help with drainage and prevent the bulbs from spreading. Finally, you can fertilize your calla lilies regularly with a bulb fertilizer that contains a high percentage of phosphorus.
This will promote blooming and discourage bulb spread.
