      Hi Sylvie,
      Thanks for contacting us. Well, you’re already on the Calamus so you must know that calamus filters the water in much the manner you’re indicating. I suppose European Speedwell, watercress, yerba mansa and brahmi could be similarly employed, but I don’t think any of them are as efficient as calamus.

      Hi Richo, just perusing your sweet catalog & came upon your calamus offering ~ are you sure of your ID of the plant in the photo? I would call it Acorus calamus (the European species) because only the midvein is raised on the leaves. My understanding is that on Acorus americanus (the North American native) all the veins on the leaves are raised. From what I have read, there is more of the European species here in the U.S. ~ I love the plant & used to sell both species. I have visions of Native Americans planting A. americanus along their migratory paths. And, I could be wrong about the identification but that’s what I remember. Would love your thoughts.

      Hi Jane, Very nice to hear from you. We collected the original stock from a wild patch in saskatchewan–its probably the american species. We analyzed it via HPTLC and confirmed low beta asarone content. I don’t know about the raised midvein thing, but the plants are very close–the american type is often considered to be a subspecies (Acorus calamus americanus) not a true separate sp. Richo

  2. Acorus calamus var americanus

    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.
