Final Hoya hahniae comparison photo for now. After sacrificing a peduncle, which the plant would have flowered many times on, I needed to get the most from it, and I think I accomplished my mission!
Hoya hahniae and Hoya rosarioae
Both flowers are pink, but the much pinker Hoya hahniae makes Hoya rosarioae look orange. By the way, I finally had a chance to smell Hoya rosarioae without a cold, and I can say that it does indeed smell of roses!
Hoya hahniae Meets Hoya alagensis NS05-232
Hoya hahniae Meets Hoya blashernaezii ssp. Siariae
Hoya hahniae Won’t Stop Flowering Now
Hoya halconesis and Hoya alagensis NS05-232
Two must have Hoyas that grow and flower at the same time and in the same way. No artificial aids were used to get these plants to bloom.
