Last year my Hoya wightii sub. palniensis did not fare at all well inside.  It literally lost hundreds of leaves primarily because it suffered an aphid attack, did not have enough light, and suffered mightily for it.  This year I have brought it to my work space where it will have a full southern exposure.  I also noticed after moving it there yesterday morning that it has another peduncle just starting to bud up.  We will hope for the best, and I will bring you updates on the plant in the coming months.
