    Beautiful little sedge! Found something very similar growing in northeast Wisconsin last summer. Are there related species that would grow in that area?

      Hi Karen
      Very beautiful sedge. There are no closely related species that would grow in Wisconsin. However, there are two related neotropical species that grow in central and south Florida and along the Gulf Coast to Texas. The one one most similar is Cyperus elegans. The other species is C. oxylepis. These species like the one in Hawaii have sticky culms and belong to section Glutinosi

    Aloha Karen,
    The Sedge family (Cyperaceae) is a large worldwide group of plants, so there may be a similar species in that area.
    Fyi, there are 14 or 15 native species, of which 8 are endemic, or naturally found only, in the Hawaiian islands. The endemic species are tropical/sub-tropical in nature and would not survive the very cold winters of the the north & central US.
    Aloha,

    Aloha Tamara,
    I was given a handful of Hawaiian endemic sedge seeds and planted them. Well they did very well and are now everywhere, coming up in my potted plant collection, across the street, down the road, good thing they are native. Kamehameha Schools just installed a landscape project in Haleiwa using natural grasses and sedges. I am going by today and will take a picture. I enjoy your daily emails.
    Mahalo, Brynn

    Hi David,
    My name is Randy Mears and have been studying Cyperus from many parts of the world for more than 30 years and I would like to find someone who could possibly show me where to photograph C. trachysanthos. I am planning to travel to Hawaii in February or March to photograph a non native species to Hawaii- C. gracilis. I am photographing all species of U.S. mainland Cyperus species and am only missing C. gracilis and one other C. lentiginosus. Do you know of anyone who would be able and willing to show me some of the endemic Cyperus species on Oahu? In particular C. trachysanthos. This is only for photograhing and not collecting! my email is randycyperus@yahoo.com. I live in Tampa, Florida. You sound very knowledgable on the subject. If you google my name and Cyperus, you will see some of my publications.

    regards
    Randy
