    Clematis banter

    TOMATO OR TOMATO? Pardon? I thought this was about clematis.

    YES, BUT HOW DO YOU PRONOUNCE IT? Tomato?

    NO, CLEMATIS. Ah…that, my friend, is a very good question.

    AND THE ANSWER? Depends who you ask, there seem to be at least five different options.

    SO ITS NOT CLEM-AY-TIS. Well some say it that way, while in the United States its often clem-AR-tis or cle-MAT-is.

    OH NO, THATS RIDICULOUS. CANT WE AT LEAST AGREE THAT ITS EITHER CL-EM-ATIS OR CLEM-AY-TIS? Apparently not. Dr Mary Toomey, of the British Clematis Society no less, says that the classically correct pronunciation may well be cl-EEE-matis. The name comes from the Greek, it seems, klema (pronounced kl-EEE-ma) meaning a vine twig.

    THEYLL LAUGH IF I GO INTO THE GARDEN CENTRE AND ASK FOR A CL-EEE-MATIS!
    Then stick to cl-EM-atis or clem-AY-tis, theyll know what you mean. Or you may want to call it wei ling xian, though not in the garden centre.

    THEN WHERE? In the health food shop, its the Chinese name for clematis, listed as one of the ten most popular Chinese medicianal herbs.

    YOURE GOING TO TELL ME ITS USED FOR SOMETHING "FUNNY" ARENT YOU? On the contrary, its used for rheumatism and to help dislodge fishbones from the throat. And to expel wind.

    THERE, I TOLD YOU. BUT IT SOUNDS USEFUL. Except The American Pharmaceutical Association Practical Guide To Natural Medicines says If swallowed, it can bring about intense pain in the mouth, blistering, profuse salivation, abdominal cramping, severe diarrhea, bloody vomiting, kidney irritation with pain and excessive urination as well as blood in the urine, dizziness, fainting, and convulsions in severe cases.

    GIVE ME THE FISHBONE ANY DAY. So be careful what you ask for.

    NOT WEI LING XIAN, ILL STICK TO CLEM-AY-TIS. I say cl-EM-matis.

    BUT I SAY CLEM-AY-TIS OK, Lets call the whole thing off.


    Calling the whole thing off

    He says: I think the debate is descending into pointless pedantry. Richard Green, Clematis on the Web
