Huperzia is a huge fern allie family that are found threw out the old world and new world. There are so many species and I have had a hard time getting species names so If you read Spp that is just a species that I do not know what the name is. If you see one that you may know what the name is contact me I'd like to know.
Growing huperzia is not difficult and I have them in windows in my house and in business. Most like bright light and to dry out a little before watering. Most can take temperatures down in the 50's at short periods of time. Contact me if you are interested in starting your Huperzia collection.
