If any of you despair at the high auction price of Hoyas on Ebay, my suggestion to you is to wait to bid on plants until September or October.  Everyone is all hot to grow Hoyas in April, or May, but come Fall, interest has waned and plants can be picked up many times for a fraction of what they cost in spring and summer. Hoya greenii was such a purchase, where I picked it up for a song, and it turned out to be my best Hoya buy of 2016.
