I believe it depends on which parent is the pod parent (female), the one that carries and matures the seed pod and which was the pollen parent (male). If you reverse the order or pod parent vs pollen parent you will get different offspring characteristics. If your really into genetics the link below has some interesting info, a little confusing at times especially if your like I am and not all that interested in genetics.

Hi Denise, I don't know much about hybridizing either so I won't be much help there. I also have/had meredithii x crassicaulis from Gardino's...I say it that way because mine got some major cold damage (along with a few of other hoyas) this winter...so its down to two semi healthy leaves right now. I've tried re-rooting it a couple of times and still not sure if it will recover.

Both of yours are very pretty and healthy...but I'm partial to one that you received from Gardino's though...the leaves are more dramatic and showy IMO.

Here's mine when it WAS healthy BEFORE the cold damage. Unfortunately it looks terrible now :o(
