Monarch Fern
Phymatosorus scolopendria
Phymatosorus scolopendria, commonly referred to as the Monarch Fern or Wart Fern, is a hardy and attractive creeping fern native to tropical regions of the Old World. It is prized for its glossy, leathery, and deeply lobed green fronds that grow from thick, furry rhizomes. The plant is easily identified by its distinctive sori—raised orange-brown spore clusters on the leaf undersides—that create a 'warty' appearance on the upper surface. When crushed, the foliage releases a pleasant, musk-like fragrance, adding a sensory dimension to its visual appeal.

Care Guide
Monarch Fern Care Guide ### Lighting This fern thrives in bright, indirect light. While it is more resilient than many other fern species, direct afternoon sun can scorch its leathery fronds. It can tolerate medium light, though growth will be significantly slower. ### Watering Maintain consistent moisture in the potting medium. Water your Monarch Fern when the top inch of the soil feels dry to the touch. Ensure the pot has adequate drainage holes to prevent the rhizomes from sitting in stagnant water, which can lead to rot. ### Humidity and Temperature As a tropical species, it requires high humidity (50% or higher). Use a humidifier, pebble tray, or frequent misting to keep the plant healthy. Maintain indoor temperatures between 65°F and 80°F, and protect the plant from cold drafts or air conditioning vents. ### Soil and Potting Use a well-draining, airy potting mix rich in organic matter. A combination of peat moss, perlite, and a small amount of orchid bark is ideal. Repot every 2 years or when the creeping rhizomes begin to crowd the edges of the container. ### Troubleshooting Brown leaf tips usually indicate low humidity or underwatering, while yellowing fronds may be a sign of overwatering.
