In Ted Green’s Hoya catalog he states that Hoya inflata has 8-12 flowers on an umbel.  Well I guess that number can be increased to 15 now, because that is how many is on my plant.  I think semi-hydro is the way to bloom this Hoya, because I have read in several places that it is difficult to flower, but not with the conditions that I provided.  It also has a second peduncle starting to bud up.  I will have a video of the plant up soon.  So please keep an eye out for it!
