Mountain mint, also known as blunt mountain mint, is a plant that is often associated with the reputation of mints as aggressive spreaders in the garden. However, unlike true mints from the Mentha species, blunt mountain mint is not considered invasive. This means that it does not have the tendency to rapidly take over an area and crowd out other plants.
One of the key reasons why blunt mountain mint is not invasive is its growth habit. While it does slowly spread through underground rhizomes, it does so at a relatively slow pace. This means that it will not quickly overtake a garden or landscape like some other plants can. The spread of this species can be controlled by simply cutting off the underground rhizomes using a spade. By doing this, you can prevent the plant from spreading beyond its desired boundaries.
In my personal experience, I have found that blunt mountain mint is a great addition to a garden or landscape. Its attractive foliage and delicate flowers can add a touch of beauty to any space. Additionally, it has the added benefit of attracting pollinators such as bees and butterflies, which can help with overall garden health.
It is important to note that while blunt mountain mint is not invasive, it may still spread slowly over time. This can be advantageous if you are looking to fill in a particular area or create a naturalized look. However, if you prefer to keep the plant contained, regular monitoring and maintenance will be necessary to prevent it from spreading too far.
To summarize, blunt mountain mint is not considered invasive, unlike true mints. It will slowly spread through rhizomes but can be controlled by cutting off the underground growth. It can be a beneficial addition to a garden or landscape, attracting pollinators and adding beauty. However, regular monitoring and maintenance may be needed to prevent unwanted spreading beyond desired boundaries.
