I got a Hoya cutting from an elderly friend who has had the Momma Hoya (or is it Parent Hoya) for decades. It is a plain green variety. She was giving it a trim and get me a strand. I've had it sitting in water for months and months and finally I saw a few roots. I just planted the two cuttings into potting soil in the hope that once the roots got into soil the plant would start to grow. Anybody have any idea how long it should take 'til I SEE new growth?
