commonly known as Dragon's Scales, it is a common epiphytic fern. The rhizomes of the epiphytic fern are exposed to the air, grow naturally in a totally soilless condition.
Can Pyrrosia piloselloides be grown in pot? , I would be interested to hear any opinions on this.
My daughter taught me this dragon teeth name. In NTU, many of the trees have this fern growing.
They probably will grow in a pot, or use a stick and grow them like a money plant.
