Growth Around Root of Ferns
Over the root ball of my fern were pebbles like nodes over the entire area. Between the pot in which it was living and the roots, the nodes were hard, white, and cut like a potato. What are they?
They are called tubers, and they are part of the root storage system like bulbs, corms and rhizomes. Ferns, chlorophytum and potatoes all have tubers in common.
