Propagation of Botrychium lunaria (L.) Sw. ssp. minganense (Victorin) Calder & Taylor
Botrychium lunaria (L.) Sw. ssp. minganense (Victorin) Calder & Taylor, also known as moonwort fern, is a rare species of fern with small sporophytes that only reach a height of 2-4 inches. The plant has a subterranean rhizome that resembles a fleshy root. Propagation of moonwort fern can be challenging due to its small size and unique reproductive characteristics. However, there are several methods that can be used to propagate the plant effectively.
Propagation by Spores
Moonwort fern can be propagated by spores, which are microscopic reproductive structures found on the underside of the fronds. Collecting spores can be difficult due to the small size of the sporophytes, but it can be done by carefully cutting mature fronds and placing them over a piece of white paper. The spores often fall off naturally and can be collected from the paper. Once collected, the spores can be sown onto moist soil in a container and covered with plastic wrap to retain moisture. The container should be kept in a warm and well-lit area until the spores germinate and the young plants can be transplanted into individual pots.
Propagation by Division
Moonwort fern can also be propagated by division, although this method is more suitable for larger plants. To propagate by division, the rhizome must be carefully dug up and separated into several smaller sections. Each new section should have at least one healthy frond attached. The new sections can then be transplanted into individual pots or directly into the ground, providing they are planted in an appropriate location where the plant's habitat and growth requirements are met.
