If you have space for a possibly huge hoya, you might consider Hoya sp. 910307. I received this great hoya as a cuttings many years ago and it rooted easily and have never given me any problems what-so-ever. Hoya sp. 910307 is easy to grow and blooms on a regular basis, on many peduncles at one time. The flowers are a lemony yellow but I detect little if any fragrance which may be a good thing since so many flowers showing at once may become overwhelming. I just love this one and do not hesitate to take many cuttings at one time to be able to share as starter plants.
