Hoya rosarioae takes a fair amount of moisture, but growing it was completely unproblematic and it flowered between 6 and 7 months from cutting.  You can’t ask for more than that from a plant!

I purchased Hoya rosarioae as a cutting from Ric Morier of Florida in the middle of the summer growing season last year.  I grew it in a series of net pots using my regular chunky mix and it grew rapidly.

Here are a couple of close-ups of the flowers of Hoya rosarioae:

Hoya rosarioae is very similar to Hoya obscura but has smaller flowers, much longer peduncles and the pollinina are much shorter. This information comes from a Dale Kloppenburg publication, but I can attest that this plant is a different animal than H. obscura.  I have tried to grow Hoya obscura on two seperate occasions and failed – it won’t grow for me under my conditions, but Hoya rosarioae grew very easily. Below the back of the flowers:

Hoya rosarioae was named after Marylin Rosario, Los Banos, Laguna, Philippines and was published by Kloppenburg & Siar in 2009. Below the flowers of Hoya rosarioae:

Hoya rosarioae was first collected by Dr. Simeona V. Siar in the Philippines in 2007. Below the Buds of Hoya rosarioae:

As I write this it is currently -7°F and we are in a prolonged cold snap.  Life is just so much harder when it is cold like this.  Despite this awful weather I managed to get a new Hoya to bloom for me; its name is Hoya rosarioae. Here is a photo of the foliage and the entire plant to start the discussion:

While all of my Hoya manipurensis seedlings are still alive and for the most part growing well, there was one plant that has exceeded all of the others.  Pictured below is the most outstanding specimen.  It never has lost a leaf, shows the most vigor, and has grown four vines from the base of the plant.  This is the reason why seeds are not cuttings; each one is a little bit different.  If one were going to sell cuttings, this would be the plant to clone as it is many times stronger than its mother.

Here I throw Hoya wightii into the mix.

This photo is unpublished from this summer.  Flowers from left to right Hoya oblongacutifolia, Hoya quinquenervia, and Hoya hanhiae. Tomorrow I add one more bloom to the mix.
