Polystichum acrostichoides aka Christmas Fern
Taxonomy
Polystichum acrostichoides, also known as Christmas fern, is a perennial evergreen fern that is native to eastern North America. It can be found in moist and shady habitats in woodlands, stream banks, and rocky slopes from Nova Scotia to Minnesota and south to Florida and eastern Texas. The dark green fronds can reach up to 3 feet long and 4 inches wide, providing color and interest to gardens throughout the year. Its common name comes from the fact that the fronds are often still green during the Christmas season. This fern is hardy in USDA plant hardiness zones 3-9 and is relatively easy to grow as a houseplant, as long as it is kept in long-lasting, direct light and given plenty of water.

Difficulty
Christmas Fern is a low-maintenance plant that requires minimal attention, making it an excellent choice for beginners.
Soil
When growing Christmas 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 Dagger Fern with the nutrients and moisture it needs. The added organic matter will also help the soil retain water and prevent the Christmas 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 Christmas Fern regularly, making sure to keep the soil evenly moist but never soggy. With the correct soil and watering regimen, the Christmas Fern will thrive and bring lots of beauty to your home.
Toxicity
Christmas Fern is not known to cause harm to humans or pets.
Fertilizer
The Christmas 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
The Christmas Fern is clumping in nature, with new growth originating from the soil in close proximity to the original plant.
Region of origin
Christmas Fern’s native range is Eastern N. America - Nova Scotia to Wisconsin, south to Florida, Texas and Mexico.
