While this book does not talk about Hoyas per se, it does a fantastic job of helping people who never thought they had a green thumb to develop one. The book is called The New Plant Parent: Develop Your Green Thumb and Care for Your House-Plant Family and it is written by Darryl Cheng. I read it cover to cover and although I have been taking care of plants for over 40 years I still learned a thing or two from it. Anyhow this book gets my highest recommendation, and it would make a great gift for anyone who has the tiniest inclination to want to grow houseplants.
Hoya aff. kentiana is a plant that I never would have looked for, but I am really glad that I have it now. It is a very easy care, easy bloomer that would do well for any novice Hoya keeper, but would add a little spice to the intermediate growers collection as well. The long pointed leaves make a good substitute for a Hoya that I find impossible to grow in Hoya shepherdii. This plant gets my highest recommendation.
Hoya aff. kentiana grew exceptionally well in my regular Hoya mix and is a plant that also does well living as a hanging plant in a window in the house, meaning that no special provisions such as grow tents are needed for success. This is one of those Hoyas that I cannot imagine growing trellised, but if you have done it, I would love to see photos! Below my plant in its entirety:
Hoya aff. kentiana is in the Acanthostemma Section of Hoya and as such has the same wonderful butterscotch fragrance indicative to almost all the flowers in this group. They last about a week before beginning to fall off.
It can clearly be seen in the photos how much different the leaves on Hoya aff. kentiana are from Hoya wayetii. They are far longer, pointier and look very much like the leaves on Hoya shepherdii.
Late in the summer of 2018 I received a free Hoya cutting in an order from Ric Morier labeled Hoya aff. kentiana. It was not a Hoya that I ever would have sought out as I felt that it was kind of like been there done that. I however planted the cutting, which proved to be as easy as its close cousin Hoya wayetii. Below the foliage of Hoya kentiana:
Years ago I bought a Hoya labeled Hoya kentiana in one of the big box stores that grew amazing and flowered profusely over the entire summer outside. Below is a photo of that plant:
I quickly found out from people on the online Hoya forums that this plant was mislabeled and should have been called Hoya wayetii. Tomorrow the real Hoya kentiana.

I decided to take the time to find out more about the night time life of the flowers of Hoya wallachii. I have been constantly frustrated with this plant because by the time I get down to my grow tent in the morning the flowers are pretty much closed up. I took a plant whose buds were going to open very soon and moved it to an upstairs window sill where I could more closely observe it. The flower opened up at night and it never gets beyond a large bell shaped flower. Because of some photos that I have seen online that made the flowers appear to open flat like Hoya patella, I thought that is what they are supposed to do. Those photos from the internet are misleading; they never open beyond a large bell shape during the entire night. They close up during the day and open at night. This goes on for about three days before the flower no longer opens and eventually falls off. Below is a photo of a fully opened flower on Hoya wallachii:
Hoya pubicalyx Pink Dragon was covered in buds in my humid basement grow tent, and I decided to bring it upstairs and put it on to a windowsill to enjoy it. I was unsure it the buds would hold with the major change in conditions, but every single bud matured and opened over a period of weeks. Below is the last of these wonderful flowers:
