Hi Renee, first and second looks like carnosa.
Your hoyas look pretty happy so you are doing great!
I've seen lots of roots like that on some of my hoyas.

OMG, where do you live geograhically pls? Your Hoyas look like they're happy & in paradise. That'd be my explanation for those long aerial roots on the last pic. Wow, really, amazingly happy & healthy! I've never see a Bella look that healthy!

My guess is - you have it in a very humid environment... because when I put my hoyas in the aquarium to start or maybe just help them out if they are not looking good - I get these great big aerial roots coming from all over the place... are the plants in a very humid place?

Thanks you all. I wasn't sure about the first plant shown, the leaves feel so much more succulant than my other carnosas. But it has really taken off this summer.

And yes, they have very high humidity. They are outside from about April through October, and for the past month we've been very hot and humid. 90F plus with about 70% humidity. I bring them into a heated porch when the night temps starting consistently dropping below 55F.

I'm in Zone 8, in the FL panhandle, but I live less than a mile from the Gulf, so it's always pretty humid and breezy here.

The only plant I treat differently is Hoya serpens, which I leave outside until the nights go below 35F. Funny thing, it is growing a lot in this heat as well.

Here's a picture of the serpens from this past spring, and the plant has probably doubled in size since then.

oh, and I meant to add for PG, the bella there does very well as long as I don't let it start to dry at all. And I've taken quite a few cuttings from it, and when I do, it branches like crazy. My other regular bella has been blooming the past month, and now finally this one is starting to bud up. It is receiving less light than the regular bella.
