    I asked a few of my flower friends about their experiences with Tweedia and how they treat the sap that leaks from the stems..

    “I love that stuff like nobody’s business. Anything other than blue is hard to find. If I ever see white tweedia or pink Tweedia its like spotting a unicorn. I just cut it, let it leak the milky sap in a container or put it into arrangements at the end. I do pull some of those leaves off when cleaning it and yep the sap goes everywhere. I just embrace it. It’s worth it.” Alexandra of Exquisite Designs

    “I cut to approximate lengths take off leaves and let them sit in their own vase.” Laurie of Fleurie

    “I wear gloves when I’m designing with it.” Corinne of Sebesta Design

    “It’s the perfect blue without going purple. But, it’s a pain. Sticky, droopy at times, but like others have said worth the sacrifice.” Dana of Della Blooms

    “It adds a delicacy to a bouquet like nothing else can. And it’s a beautiful natural teal blue, which can be hard to find! Oh, and latex gloves were recommended by my wholesaler. My skin doesn’t mind it, but if you have sensitive skin watch out!” Chandin of Studio 3 Floral

    “Makes my hand itch like crazy. Once I received some and it was a droopy mess. Fresh cut into a vase of water with a splash of vinegar and it perked right up. Years ago an old florist told me to use vinegar to firm up gerbers and I was desperate to revive the tweedia and it worked!” Monica of Twigs Floral Design

      Tweedias, asclepias,euphorbias – I find that these benefit greatly from being cut underwater. I like the technique for all flowers, but even if you do not do it for most of your flowers, the flowers that have milky sap are helped immensely by the basic physics of cutting underwater. Minimal sap is excreted because underwater the sap cannot be displaced from the stem. So not only is the initial cut better for the flowers but the sap loss is very little, remaining in the stem where it is of great benefit to the flower.
