Calamus (Acorus calamus var americanus) Potted Plant, organic


Family:  Arum (Araceae)

Zones 4 to 11

Plant prefers pond, streamside or moist or sodden soil—excellent filter plant in pondscapes, it will clarify yucky water and promote health of any waterway or pond. Plant prefers full sun to part shade and moist soil or shallow water at the edge of the pond.  Just press the rhizome and rootlets down into the mud with the green shoots pointing up toward the sun and you will see great results.

  1. Acorus calamus var americanus

    Vicki Fisher

    I have a bog (and a shallow one at that)- to be safe I bring some calamus in with my other tropical plants during the winter. It does not love it, but it survives just fine. So does the calamus out in my 8-10″ deep bog! I harvest plenty of root (It’s been two years now) and leave a few plants and there is far more than what I started with. It does indeed help water quality as well, I have gone through phases of wanting an actual pond and I can do that with calamus, fish and no filter.
