Horsetail
Horsetail plants can easily tolerate a wide variety of conditions, such as those where the soil is completely wet. In the wild, these plants can easily grow in wet woodlands, but also alongside small bodies of water. They usually grow 2 to 4 feet tall, sometimes even with a 6-foot spread.
Even more, under the right circumstances, they can turn out to be aggressive spreaders, so it’s highly important to completely remove its rhizomes, which are underground stems that will send up new shoots, from the places you don’t want the plant to expand. What do you think about this plant? I think it doesn’t get more low maintenance than this!
