Invasive Perennials
Here are five of the most invasive plants you may want to think twice about planting.
Lily of the Valley
You may be familiar with lily of the valley (Convallaria majalis) because of its appearance in many royal bridal bouquets and most recently carried by the Duchess of York.
Japanese Anemone
Most of us don’t think of anemones as a fall flower. These tall, graceful stems with delicate, umbrella-like petals remind most of us of spring or summer.
Yarrow
You have seen yarrow in many bridal bouquets in the last ten years or so. It looks like a wildflower and has a bright yellow, red, white or light pink color. The tiny flowers grow in large, umbrella-shaped clusters, so each stalk can take up a large surface area.
Ferns
I don’t know why ferns have a reputation for being difficult to keep alive. In cool climates, these plants are impossible to dig out and can become the most dominant plant in a forest or even moderately shady location.
Creeping Bellflower
Ladybells or false campanula are one thing: they look sort of like a purple lily of the valley. These guys aren’t invasive, they are good in partial shade and they don’t take a lot of care. They can sometimes be aggressive. However, they aren’t even close to the invasiveness of the creeping bellflower (Campanula rapunculoides).
Conclusion
It can be hard to say goodbye to any beautiful plant – and each of these qualifies as that easily. The problem comes when a plant wants to colonize every area of the world. We know that biodiversity is actually better. Try keeping these invasive perennials to a minimum by planting them in pots or not at all.
