Calamintha nepeta, also known as Calamint, is a member of the mint family and is known for its spreading habit. However, it is important to note that while Calamintha can spread, it is not considered invasive like some other plants.
One of the noteworthy characteristics of Calamintha is its fragrant leaves, which emit a pleasant aroma when touched or brushed against. This makes it a popular choice for gardeners who appreciate scented plants.
In terms of care, Calamintha thrives in full sun or part shade and prefers moist but well-drained soil. It is relatively adaptable and can tolerate a range of soil types, including clay and sandy soils. It is also drought-tolerant once established, making it a low-maintenance plant.
When it comes to invasiveness, Calamintha does spread through rhizomes and self-seeding, which means it can gradually expand its presence in the garden. However, unlike invasive plants, Calamintha does not aggressively take over and crowd out other plants in its vicinity.
I personally have experience growing Calamintha in my own garden, and I have found it to be a well-behaved plant that stays within its designated area. It has not shown any signs of invasive behavior or caused any issues with neighboring plants.
To summarize, Calamintha is not considered invasive, although it does spread through rhizomes and self-seeding. It is a fragrant plant with attractive leaves and can be easily maintained in full sun or part shade with moist but well-drained soil. Its spreading habit is not aggressive or problematic, making it a suitable choice for gardeners who want a plant that can fill in spaces without becoming invasive.
