As a gardening and landscaping expert, I can provide you with detailed information about the invasiveness of Bigroot Geranium (Geranium macrorrhizum). Bigroot Geranium is a low-maintenance groundcover that gently spreads, making it a suitable choice for areas where you want a non-invasive plant to fill in the space.
Unlike some other groundcovers, Bigroot Geranium has a moderate growth rate and does not aggressively take over its surroundings. It forms clumps and slowly spreads through rhizomes, which are underground stems that produce new plants. This spreading habit allows it to fill in empty spaces and create a lush carpet of foliage.
However, it’s important to note that Bigroot Geranium is not considered invasive in the traditional sense. It does not pose a threat to native ecosystems or crowd out other plants. Instead, it serves as a reliable and attractive groundcover option that can suppress weeds and provide a green backdrop for other garden plants.
In my personal experience, I have found Bigroot Geranium to be a well-behaved plant in my garden. It has not shown any signs of aggressive spreading or invasive tendencies. I have planted it in areas where I wanted a low-maintenance groundcover, and it has thrived without becoming a nuisance.
When considering whether to plant Bigroot Geranium, it’s important to assess your specific gardening needs and the characteristics of your space. If you have a small garden and are looking for plants that prioritize flowers over foliage, Bigroot Geranium may not be the best choice. While it does produce delicate pink or purple flowers in late spring to early summer, its main appeal lies in its attractive leaves and spreading habit.
To summarize, Bigroot Geranium is not considered invasive and can be a valuable addition to a garden where a non-aggressive groundcover is desired. Its gentle spreading nature and low-maintenance qualities make it a suitable choice for filling in empty spaces and suppressing weeds. However, if you’re looking for a plant that prioritizes flowers in a small perennial garden, there may be better options available.
