The common name for Rumohra adiantiformis is leatherleaf fern. This plant is characterized by its glossy, deep green fronds that display a delicate and feathery appearance. The individual fronds are compound, meaning they are divided into smaller segments, which are called pinnae. These pinnae are arranged alternately along the main stem, giving the frond a ladder-like structure, and their edges are typically smooth. The texture of the fronds is somewhat leathery and they possess a certain rigidity while still appearing lush and full. The central stem, also known as the rachis, is sturdy and supports the fronds well. The overall shape of the fronds is triangular or lance-shaped, tapering towards the tip. When observed up close, the veining is often visible and forms a delicate network pattern across the fronds. The fronds can have a slight arch, creating an elegant and graceful silhouette for this fern.

  • water dropWater

    Leatherleaf fern should be watered deeply whenever the top inch of soil feels dry to the touch, which typically means once every week or two, depending on the humidity and temperature of the environment. It is essential to use lukewarm water and to water the plant until excess water drains from the bottom of the pot, ensuring that the roots are thoroughly moistened. On average, this equates to around 16-24 ounces of water for a medium-sized plant. In hotter seasons or drier conditions, you may need to water more frequently to maintain consistent soil moisture.

  • sunLight

    Leatherleaf fern thrives in indirect light or partial shade, ideally placed in a north-facing window or a spot that is shielded from direct sunlight. The best spot for this plant would be one that receives bright, filtered light for several hours each day without exposure to harsh midday sun, which can scorch its delicate fronds.

  • thermometerTemperature

    Leatherleaf fern prefers a moderate to warm environment with temperatures ranging between 60 and 80 degrees Fahrenheit. It can tolerate a minimum temperature of about 50 degrees but should be protected from sudden cold drafts and temperatures below this range. The ideal temperature promotes healthy growth and prevents cold damage.

  • scissorsPruning

    Pruning Leatherleaf fern is generally done to remove any dead or damaged fronds, promote bushier growth, and maintain an attractive shape. It's best to prune in the spring or early summer when the plant is actively growing. Cut the fronds back to the base of the plant, and you can prune once every year or as needed to tidy up the fern.

  • circleLife cycle

    The life of the leatherleaf fern, Rumohra adiantiformis, begins with spore germination, where haploid spores released from the parent plant's sporangia grow into a small heart-shaped prothallus, or gametophyte. This gametophyte houses both the male (antheridia) and female (archegonia) reproductive structures. Upon fertilization, which requires a moist environment for the sperm to swim to the egg, a new diploid sporophyte emerges and gradually develops into a young fern. The young fern continues to grow, unfurling its characteristic fronds via a process called circinate vernation, where the young fronds emerge tightly coiled and slowly unfurl as they mature. Once mature, the fern produces sporangia, typically found on the undersides of the fronds, completing the reproductive cycle as it releases spores to propagate the species. Throughout its life, the evergreen leatherleaf fern thrives in humid environments, often spreading vegetatively through underground rhizomes in addition to its sporic life cycle.

      Spring to Summer

    • The Rumohra adiantiformis, commonly known as the leatherleaf fern, is commonly propagated through division, which is the most popular method for this plant. The best time to propagate the leatherleaf fern by division is during the spring or early summer when the plant is actively growing. To propagate by division, carefully remove the fern from its pot and gently separate the rhizomes, ensuring each section has at least a few fronds and a portion of root attached. These sections can then be potted into individual containers filled with a well-draining potting mix. It is important to maintain consistent moisture and place the new plants in indirect light until they establish and begin to show new growth. This non-invasive approach allows gardeners to expand their collection of leatherleaf ferns or share with others.
