I can answer that question for you. Marginal Wood Fern, also known as Dryopteris marginalis, does not spread by runners and is not an aggressive plant. Unlike some other fern species, it does not have a tendency to take over or invade other areas of the garden.
Native to eastern North America, Marginal Wood Fern can be found growing naturally in shaded crevices of rocky ledges and bluffs. It has adapted to survive in these rocky habitats, which often have poor soil and limited moisture. This fern has developed a remarkable ability to tolerate drought, making it one of the most drought-tolerant species among the Wood Ferns.
The lack of spreading runners means that Marginal Wood Fern tends to stay in a clump or cluster, rather than spreading outwards. This can be beneficial in a garden setting, as it allows for better control and containment of the plant. You can choose where you want to plant the fern and have confidence that it won’t aggressively spread beyond that area.
Personally, I find Marginal Wood Fern to be a wonderful addition to shaded areas in the garden. Its delicate fronds and vibrant green color bring a sense of beauty and tranquility. The fact that it doesn’t spread uncontrollably is a definite plus for me, as I like to have control over the plants in my garden and prevent any aggressive spread.
To summarize, Marginal Wood Fern does not spread by runners and is not an aggressive plant. It is native to eastern North America and can be found naturally in rocky crevices. Its ability to tolerate drought makes it a valuable addition to gardens with limited moisture. Its clumping growth habit allows for better control and containment in the garden.
