Foam flower, also known as Tiarella, is a beautiful plant that is commonly used in gardens and landscaping. One of the concerns many gardeners have when introducing a new plant into their landscape is whether or not it is invasive. In the case of foam flower, I can assure you that it is quite well-mannered and not at all invasive.
Unlike some other plants that can quickly take over an area, foam flower has a spreading quality that is more controlled. The spreading nature of foam flower belongs to the true species, Tiarella cordifolia, which tends to stay in a confined area and not spread aggressively.
One of the reasons why foam flower is not invasive is because its roots are shallow, near the surface of the ground. This means that cultivating near the plants can be detrimental, as it may damage the delicate root system. However, it also means that the plant is less likely to send out invasive runners or suckers that can quickly populate an area.
In my personal experience, I have found foam flower to be a well-behaved plant in my garden. I have planted it in both shaded areas and partial sun, and it has never shown any signs of becoming invasive. It forms neat clumps of foliage and delicate flowers, adding a touch of beauty to the landscape without taking over.
It is important to note that there are different varieties of foam flower available, and some may have slightly different growth habits. However, in general, foam flower is not considered invasive and is a safe choice for most gardens.
To summarize, foam flower is not invasive. Its spreading quality is more controlled, thanks to its shallow roots. It is well-behaved in gardens and does not aggressively spread or take over. In my personal experience, I have found it to be a delightful addition to my landscape, adding beauty without any invasive tendencies.
