Polystichum lonchitis aka Holly Fern

Taxonomy

Polystichum lonchitis, commonly known as Northern Hollyfern, is an evergreen fern native to the Northern Hemisphere from Eurasia to Alaska, Greenland and south into mountainous central North America. Its stiff, glossy green, erect fronds prefer a moist, shady, rocky mountain habitat. As an houseplant it is rare and needs lots of water to thrive, preferably in long-lasting, direct light, less than one foot away from a window. The soil should be good at retaining moisture and no fertilizers are needed if it is repotted when it doubles in size.

Common names

Holly Fern, Northern Holly Fern, Northern Hollyfern

How to care for Holly Fern

Difficulty

Holly Fern requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.

Soil

When growing Holly Fern, it is important to pay attention to the soil type you are using. This plant is very sensitive to dry soil and needs a potting soil that retains moisture. A good soil should still be well-draining and contain lots of organic matter. Coco coir or sphagnum moss are great options to provide the Northern Hollyfern with the nutrients and moisture it needs. The added organic matter will also help the soil retain water and prevent the Holly Fern from drying out too quickly. Before planting, make sure to mix compost or manure into the soil for extra nutrients. Also, make sure to water the Holly Fern regularly, making sure to keep the soil evenly moist but never soggy. With the correct soil and watering regimen, the Holly Fern will thrive and bring lots of beauty to your home.

Lighting

To ensure optimal growth, the Holly Fern prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Toxicity

Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.

Fertilizer

The Holly Fern should be repotted either when it doubles in size or annually, whichever comes first. Providing new potting soil with all the vital nutrients annually is enough to support the growth of the plant, and thus, there is no need for fertilizer. Remember that plants derive their energy from the sun, not fertilizer.

Growth-pattern

New growth will sprout from the top of the plant as it grows upwards.
