Wildcat, is that Krinkle I see there? We have one and it used to go all the way down our front eves but I took the nippers to it so now I have many plants!
Wildcat the top 2 photos it appears to be the Krinkle and the bottom 3 appears to be the Compacta. Are they all taken of the same plant? Krinkle is sure the waver of the two. Beautiful plant and one has got to love them for their blooms! They sure get heavy once you start winding them upward around the pot so they don't drag on the ground. Ours were 12 years old before we cut them back. Have you tried to root a leaf?
First two pictures was the one I was referring to that the debate was about.
The second three pictures are of a different plant. I thought it was just a common hoya. It is much different from the other one, in the way the flowers look, the growing habit, flat smooth leaves, very vine like, etc.
I really do not know what they are, but they grow easily and flower extremely well.
They have a few dozen large hanging baskets of both of them for sale cheap at the greenhouse near me from cuttings of these two plants.
