What is Giant Holly Fern or Sword Fern?
Giant Holly fern (Polystichum munitum), is known for its other names like Sword fern, Western sword, and imbricate sword fern. It is an evergreen fern that originated in Western North America where is it also the most common. This fern has become a native plant in parts of Great Britain and Ireland.
This fern has dark green fronds that reach heights of 50 to 180 centimeters and form a compact cluster that radiates out from a circular base. The pinnae alternate on the stalk, and they are single-pinnate. Each pinna is 1 to 15 centimeters long and has a bristly tip at the edge, a short upward-pointing lobe at the base that resembles a sword hilt, and a serrated edge.
It thrives in acidic, well-drained soil that contains tiny stones and abundant humus. It is quite hardy and can endure brief periods of drought, but it thrives primarily under conditions of continuous rainfall and low levels of sunlight. It also enjoys cool temperatures.
Keeping Cats Away From Giant Holly Fern or Sword Fern
The location of your plants must be considered carefully.
Fortunately, sword fern works well with hanging plants. Place hanging baskets throughout the room to add liveliness, but make sure the plants are out of your cat’s reach at all times.
A colorful fern can also appear completely at home on a high shelf, out of reach of prying paws.
Aluminum foil can be another effective way to stop your cat from becoming obsessed because cats often don’t enjoy how it feels, tastes, or smells. Try wrapping the pot in foil or covering the soil with crumpled foil.
