Salvias are a group of plants that come in many different species and varieties, and they are known for their vibrant colors and the attractiveness they add to gardens. However, there is a lot of confusion surrounding the spreading habits of these plants, with some sources claiming that they are invasive, while others suggest that they do not spread readily at all.
In the article, Are Salvias Invasive? Understanding Their Spreading Habits. We will take a closer look at the different types of Salvias and their spreading habits to help you better understand whether they can become invasive in your garden.
What Are Salvias?
Before we delve into the topic of Salvias’ spreading habits, it’s important to define what these plants are. Salvias are a genus of plants that belong to the mint family, Lamiaceae. There are over 900 species of Salvias worldwide, with many different colors, shapes, and sizes. Some of the most popular Salvias include Salvia lyrata, Salvia officinalis, and Salvia divinorum, among others.
Types of Salvias and Are Salvias Invasive
Salvias can be divided into two main categories: native and non-native. Native Salvias are those that are naturally found in a particular region and have evolved over time to adapt to the local environment. Non-native Salvias, on the other hand, are those that have been introduced to a region and may not have any natural predators or competitors.
Understanding Their Spreading Habits of Salvia
Salvia is a genus of plants that contains over 900 species of herbs and shrubs, most of which are native to the Northern Hemisphere. While salvia is not normally considered an invasive species, certain species can become invasive in certain climates.
In the United States, salvia species such as Salvia reflexa, Salvia lyrata, and Salvia coccinea can become invasive in some regions . However, salvias are generally not considered invasive as they do not spread very readily for the most part and will remain in the location where they are planted . While some species can grow rapidly and reach up to 5-6 feet in a season, others are low-growing and can be used along flower bed edges.
Depending on the species, salvias can range in width from 12 inches to 4 feet . Therefore, the extent of the spread is unlikely to cause significant problems in your garden. It is important to check the specific species of salvia before planting them to ensure that they are suitable for your region and will not become invasive.
There are several Salvias that are considered invasive due to their aggressive spreading habits. These include:
Salvia lyrata, also known as lyre-leaved sage, is a native plant to the southeastern United States. This plant can grow up to two feet tall and has purple-blue flowers. It is considered invasive because it can quickly spread and dominate native plant communities, reducing biodiversity. 
Salvia Arenaria, also known as sand sage, is a native plant to the western United States. This plant can grow up to four feet tall and has yellow flowers. It is considered invasive because it can displace native plants and alter ecosystem processes. 
Salvia pratensis, also known as meadow sage, is a native plant to Europe. This plant can grow up to three feet tall and has blue-violet flowers. It is considered invasive because it can form dense stands and outcompete native plants. 
Salvia divinorum, also known as diviner’s sage, is a non-native plant from Mexico. This plant can grow up to six feet tall and has purple flowers. It is considered invasive because it can escape cultivation and establish itself in natural areas, potentially disrupting local ecosystems. 
Salvia miltiorrhiza, also known as red sage or danshen, is a non-native plant from China. This plant can grow up to three feet tall and has red flowers. It is considered invasive because it can form dense stands and displace native plants in wetland habitats.
What Are Invasive Salvias

However, not all Salvias are invasive. In fact, Salvias are generally considered to be non-invasive . While there are some species that can be mildly invasive in certain regions of the country, they are not typically considered a significant problem.
For example, Salvia Ethiopia is considered invasive in parts of Colorado, Washington, Oregon, Arizona, California, Idaho, and Nevada .
It’s worth noting that some Salvia species are simply more aggressive than others. For example, Salvia lyrata and Salvia arenaria are known to spread quickly and can be difficult to control .
