Hi Inger...welcome to the forum! Very nice blooms/hoyas! I don't grow the first one so I'm not positive. The second one looks almost exactly like my Carnosa 'moteskei'...beautiful plant and blooms! That's so neat that your grandma would have turned 100 today and so special that you inherited her hoya...Enjoy!

Others will be able to give you a positive ID on your first one.

What a great story about your Hoya, I am sure you will cherish your plant for a long time to come.
Your plant is Hoya javanica. If you look at the central portion of the flower, the corona, it's lobes at their tips are bent outwards. In Hoya multiflora the tips of the corona lobes are bent inwards. There is also a species called Crytoceras floribumdum which is similar to Hoya javanica , you can read about them all in an older thread.

You are right, your second plant is Hoya carnosa.

Thank you :)
Yes, Mike, I cherish my javanica! And specially after it bloomed again. I just recently found out it`s a hoya at all, I thought all hoyas have thick leaves like my other...

Year after year it got buds, wich would fall off at different stages og developing. Still not sure what was different this time! It`s in a pot without a hole in the bottom, maybe I should repot it? I will def try to grow a few cuttings.
