Beware: some plants may look pretty and innocent, but in reality have the ability to ruin your yard. Invasive plants are an example of having too much of a good thing. These plants can grow so well that they quickly overtake all your surrounding plants and before you know it, you’ll find it’s the only thing growing. Here are a few plants you should think twice about before including in your garden.
1. Calla Lilies
This attractive, lush plant is known for its glossy, wide leaves and stunning trumpet-shaped flowers. In regions where winter temperatures are above freezing these lilies will spread throughout your garden and shade out any surrounding plants. If this applies to you, your best bet is to put these pretty plants in a separate garden to prevent them from getting out of control.
2. Bachelor Buttons
Also known as cornflowers, this stunning periwinkle blue plant is a problematic self-seeder. This means if you don’t cut off the blossoms of your Bachelor Buttons before they dry up and release their seed, you will find your lawn full of them before you know it.
4. Mimosa Tree
With their feather-like leaves and bright pink flowers, the Mimosa Tree is an absolutely beautiful plant. However, looks can be deceiving. If you plant one of this incredibly invasive species of plant, the seedlings will spawn not just in your yard, but throughout your entire neighborhood. Once the seeds have spread, it is nearly impossible to contain.
5. Rose of Sharon
This attractive shrub is incredibly invasive. The blossoms turn into fruit with seeds pods that spread abundantly in the wind. Rose of Sharon is hearty and tend to sprout up quickly on its way to soon take over your yard.
Native to Japan and China, this vine grows well in the southeastern United States. Kudzu will spread so quickly that over the course of several years, it will kill trees by blocking the sunlight. Additionally, Kudzu vines will cover buildings over many years if not controlled. You can see evidence of this in the southern United States where many abandoned homes are covered with Kudzu.
While this herb is great to grow on its own in a pot so that it is readily available for you to use, if you plant mint in the ground, it will send out stubborn runners that will choke surrounding plants. You’ll find mint sprouting up around other plants—even years after removing it.
8. Ox-Eye Daisy
This sunny white and yellow variety of daisy grows in low shrubs and is so invasive that it’s banned for sale in 10 U.S. states. While they may look pleasant, if you’d like a white daisy for your garden, grow Shasta daisies - they will create a similar aesthetic without taking over your yard.
Technically a giant grass, bamboo is one of the world’s most invasive plants. The sprouts that shoot up from the ground can grow 12 inches a day. Even worse, the underground roots of the common “fishpole” bamboo can easily reach 15 feet tall.
10. Autumn Olive Will Ruin Your Yard
This shrub is a threat to natural ecosystems by out-competing and displacing all native plant species. It creates a dense shad which interferes with natural pant succession and nutrient cycling. It also can produce up to 200,000 seeds a year, allowing it to spread over a variety of habitats, reproducing quickly and uncontrollably.
