Synonyms of Nephrolepis exaltata (4) (Updated on 2-8-21): Aspidium exaltatum (L.) Sw., Hypopeltis exaltata (L.) Bory, Nephrodium exaltatum (L.) R.Br., Polypodium exaltatum L.

Nephrolepis exaltata (L.) Schott is the correct and accepted scientific name for this species of fern. The genus and species were named and described as such by Wilhelm Heinrich Schott in Genera Filicum in 1834. It was first named and described as Polypodium exaltatum by Carl von Linnaeus in Systema Naturae in 1759.

Plants of the World Online by Kew lists 29 accepted species in the genus Nephrolepis (as of 2-8-21 when I am updating this page). It is a member of the plant family Polypodiaceae with 65 genera. Those numbers could change as updates are made.

Since I wrote this page and have been doing updates, this fern had been listed in six different families… It is certainly not uncommon for a few websites to have different family names with all the polygenetic testing going on. I am not complaining about the testing because it is a necessary thing. BUT SIX DIFFERENT FAMILY NAMES! Some all at the same time! I know many websites do not update that often, or at all and I get behind myself. I hadn’t updated this page since 2018. A lot has changed in the scientific world of plants over the past few years and is continually updating.

WHERE WAS I? OH YEAH. Nephrolepis exaltata!

Dr. Skinner bought these two ferns from Lowe’s before she passed and I kept them until I moved from Mississippi in February 2013. We had our ups and downs every year as most people do who have overwintered these plants. By the time they start looking AWESOME it is time to bring them inside for the winter. I have been told that “MOST” people don’t bring them in for the winter and just buy new ones in the spring. That is a very good idea…

USEFUL INFORMATION:
Family: Polypodiaceae ???
Origin: Confused about that, too.
Zones: USDA Zones 9a-12 (20 TO 50° F) (some say 10a-11b)
Size: 24-36” fronds. Much larger in native habitat.
Light: Part-shade
Soil: Well-drained potting mix.
Water: Average water needs but the soil needs to be consistently moist.

All winter long you have to keep them sprayed because they need LOTS of humidity. Despite that, they will lose A LOT of their leaves and the dead fronds have to be kept cut out. If you don’t this plant will look like a disaster. Despite all the trouble you may experience overwintering them, they look AWESOME when they do look good. I like a nice-looking Boston Fern but they takes a lot of work…
