Native Plant Alternatives to Morus alba (White Mulberry)

Morus alba, commonly known as white mulberry, is considered invasive in many regions. Native to China, it was introduced into the United States during colonial times in an attempt to establish a silkworm industry.

The white mulberry is highly adaptable and can often grow in disturbed sites where it outcompetes native vegetation. Its seeds are readily dispersed by birds, which aids its spread. The tree can also produce root suckers that can lead to dense thickets.

White Mulberry is listed in the Invasive Plant Atlas of the United States.

In the United States, it’s particularly problematic in the Midwest and Eastern states but is found throughout much of the country. It’s considered an invasive species in areas like Ontario, Canada, as well. It should not be planted where it could escape into natural habitats, and existing populations should be controlled to prevent further spread.

According to the U.S Forest Service, Invasive species have contributed to the decline of 42% of U.S. endangered and threatened species and 18% of U.S. endangered or threatened species. Invasive species compete directly with native species for moisture, sunlight, nutrients, and space. They displace and alter native plant communities, degrade wildlife habitat and water quality, and potentially lead to increased soil erosion.

The federal government has estimated that nearly 25 percent of the 20,000 plant species native to North America are at risk of extinction, many of these through habitat loss. You can help reverse this trend by planting great native plants in your garden.

A plant is considered native if it occurs naturally in a particular region or ecosystem without human introduction. There are many benefits to growing native plants. First, these plants are better adapted to soils, moisture, and weather than exotic plants that evolved in other parts of the world. They need fewer fertilizers and pesticides or use less water. Second, they are unlikely to escape and become invasive, destroying natural habitats. Third, they support wildlife, providing shelter and food for native birds and insects, while exotic plants do not.
