Of the 10 plants that I picked up four weeks ago from Thailand, The plant that I thought would be among the most difficult has shown the most new growth. Hoya medinifolia has developed a sucker that is growing out of the base of the plant and also has a couple of new leaves growing on the top.  I think that my choice of trying this one in sphagnum and bark may have been the correct one. Please excuse the lousy photographs, but I was pinched for time.
