Onoclea Sensibilis | Sensitive Fern
Onoclea Sensibilis, also known as the Sensitive Fern, displays long-stemmed pale green fronds. Unlike many perennial ferns, it is actually very sensitive to frost, which gives it its name. This fern thrives in fairly dry ground as well as damp areas, where it can spread to form a dense carpet over the water surface. It grows best in slightly dry to damp mud, but not in water-logged conditions, and prefers a sheltered position. Old foliage should be tidied as needed.
The Sensitive Fern is commonly used for decorative purposes around ponds and water features.

The Sensitive Fern adds a nice green texture to my pond. It spreads slowly but steadily and looks natural in the damp areas. I’ve trimmed a few old fronds each spring and it’s been thriving since installation.

Grew well in a sheltered corner of my pond. The fronds are pale green and spread nicely. I keep the area slightly damp and avoid frost exposure. A good choice for a low-maintenance pond plant.

Very satisfied with this fern. It’s delicate but hardy in its preferred conditions. I planted it near the pond edge where moisture is consistent and it’s now forming a nice carpet.
