I doubt it. Unless you are dealing with naturally submerged aquatics you will probably drown them through lack of oxygen. My Website

I'm using the mosses and wild ferns I've gathered in a terrarium and dish garden for show. I really don't want to share any nasty critters, like thrips or mites, with other exhibiters at the show, and I'd like to also use the extra moss with my African violets and other gesneriads. Can I use Marathan and/or Avid without harming the moss and ferns? Any assistance is again appreciated. Betty Ferguson

I have been stoping on the side of the road--woods area and gathering it. I havegathered enough to go in between my rocks on a path that I recently had installed. This time of year it is very easy to spot on the side of the road. Be sure to get enough of the medium it is on. I am new to this and read to keep it moist. Also do not water with just tap water. I have a connector to my hose to remove the chlorine. I am plannig to hook up a misting system soon.

No. What you have is Lycopodium digitatum. Were you planning to grow it in your yard? Be forewarned that it is a VERY difficult plant to transplant successfully, even with years of experience in growing it. Otherwise I would recommend taking it back to where you found it and replant it and hope it survives all the shock. For more info and images check the link below.
