Dwarf Crested Pyrrosia , P. lingua var obake nana (sometimes called cristata) is easy to cultivate. I have maintained this variety for over 8 years and have never experienced any problems with its care. It is a good grower, but slower to fill out a basket than the Large Crested form, This cultivar produces very much smaller fronds, half the size of Obake. At maturity, individual leaves can be 9-10 inches long and 5-6 inches across at the crest. The blades are thinner than other forms of lingua. The fronds are very symmetrical with no twisting of the blade or crested portion. It is mostly sterile and very rarely produces fertile fronds with spores.
Attention, before purchasing any plant on line, it is wise to email me to be certain this is currently available. I have a limited number of divisions to sell annually. Click my name below to send an inquiry, thanks
