What is the invasive plant that looks like corn?

Invasive plants can be a challenge to deal with in gardening and landscaping, and one such plant that resembles corn is shattercane. This coarse grass is known for its striking resemblance to grain sorghum and corn, making it important to be able to identify and differentiate it from desirable plants.

Shattercane typically grows in tufts, forming clumps that can reach heights of almost 7 feet (2m). Its stems are erect and round, occasionally showing purplish spots, and are unbranched with solid internodes. These characteristics help distinguish it from corn, which has a more structured and branched stem. The leaves of shattercane are bright green and can be easily recognized by their white midvein, a feature that sets them apart from corn leaves.

When encountering an invasive plant like shattercane, it’s crucial to take appropriate action to prevent its spread and minimize its impact on the surrounding ecosystem. Here are some steps you can take to address this invader:

1. Identification: Familiarize yourself with the distinguishing features of shattercane, as mentioned above, to accurately identify it when you come across it. Being able to differentiate it from desirable plants like corn will help you take appropriate measures.

2. Removal: If you find shattercane in your garden or landscape, it’s important to remove it promptly. Digging out the entire plant, including its roots, is an effective method. Be sure to dispose of the plant properly, preferably by burning it or bagging and disposing of it in a designated plant waste area.

3. Prevention: To prevent the spread and reinfestation of shattercane, it’s essential to take preventive measures. Regularly inspect your garden or landscape for any signs of this invasive grass and promptly remove any found individuals. Additionally, practicing good weed management techniques, such as mulching and proper spacing of desirable plants, can help deter the growth of shattercane and other invasive species.

4. Monitoring: Keep an eye on your garden or landscape, even after removing shattercane. Invasive plants can be persistent, and it’s important to monitor for any regrowth or new seedlings. Early detection and immediate action can prevent the establishment and spread of this invasive grass.

Personal Experience:
I have encountered shattercane in my own garden, and initially, I mistook it for corn due to its similar appearance. However, upon closer inspection, I noticed the differences in stem structure and leaf characteristics. I promptly removed the shattercane plants, ensuring to dig out the roots to prevent regrowth. To monitor the area, I kept a vigilant eye and conducted regular inspections to catch any potential regrowth early on. By taking these steps, I was able to prevent the spread of shattercane and maintain the health and aesthetics of my garden.

Shattercane is an invasive grass that closely resembles corn, making it important to be able to identify and differentiate it. By understanding its distinguishing features and taking appropriate action, such as removal and prevention measures, you can effectively manage and control this invasive plant in your garden or landscape. Stay vigilant and proactive to ensure the health and beauty of your outdoor space.
