Hoya phuwuaensis Comes Alive

I don’t know what to say about this plant; it will sit there for months and months without growing at all, and then suddenly come alive.  My plant has acted just like a plastic plant for at least eight months; I almost got rid of it.  Now I’m glad I didn’t as it has just put on 4 new leaves, six peduncles and has just flowered. The flower is shown below with photo of plant:
