Pycnanthemum muticum, also known as blunt mountain mint, is a plant that is often mistaken for true mints due to its similar appearance. However, unlike the notorious invasive nature of many mint species, blunt mountain mint does not pose the same threat to your garden.
While it is true that blunt mountain mint can spread slowly through rhizomes, it is not considered invasive. This means that it will not aggressively take over your garden or choke out other plants like some mint species tend to do. Instead, it will gradually expand its presence through underground rhizomes, but at a manageable pace.
If you find that the spreading of blunt mountain mint is becoming unwanted or getting out of control, there are measures you can take to control it. One effective method is cutting off the underground rhizomes using a spade. By carefully digging around the plant and severing the rhizomes, you can prevent further spread and contain the plant to a desired area.
It is important to note that controlling the spread of blunt mountain mint should be done with care, as it is still a valuable plant in the garden. Its attractive foliage, aromatic leaves, and pollinator-friendly flowers make it a desirable addition to any landscape. Additionally, its ability to attract beneficial insects and repel pests can be beneficial for overall garden health.
In my personal experience, I have found blunt mountain mint to be a delightful addition to my garden. Its minty fragrance and beautiful blooms have attracted a variety of pollinators, such as bees and butterflies. I have not encountered any major issues with its spreading, as it has remained well-behaved and manageable. However, I do periodically check for any signs of excessive spreading and take necessary steps to control it if needed.
Blunt mountain mint, or Pycnanthemum muticum, is not invasive like true mint species. While it can slowly spread through rhizomes, it is not aggressive and can be controlled by cutting off the underground rhizomes using a spade. Its attractive qualities and beneficial properties make it a valuable addition to the garden, and with proper management, it can be enjoyed without causing any significant issues.
