    I received my H. obscura in a trade in late 2007. This is a great Hoya with a very sweet, fragrant bloom. Unfortunately this is one of the plants I lost to an unusual winter freeze.
  • Posted by Ispahan (Chicago - Zone 6a) on Nov 6, 2011 12:13 PM concerning plant:
    Hoya obscura is one of my all-time favorite houseplants. It has beautiful foliage and a seemingly never-ending supply of flowers, and the scent is rich, sweet, pervasive and altogether lovely, especially at night. It is easy to grow and relatively restrained in growth (compared to certain other members of the Hoya genus) and I would never again want to be without it!

    H. obscura asks only for ample moisture in an extremely well-drained potting mix, warm temperatures, and protection from direct sunlight during the hottest part of the day (morning and late afternoon sun are fine, however). This species propagates readily from stem cuttings, whether in water, in soil or in a sterile medium (such as perlite). I have no idea why it is not more widely known...
