I originally had posted this plant in the Plant ID forum, but have a new question, a year later...

The thread "So, what is this plant?" in Plant ID forum

Update: As time went on, root rot had already set in at that point last year, and I ended up taking cuttings. Phew! Because the original plant ended up dying.

Here is the new plant from cuttings started in water. I then transferred the cuttings to soil and they didn't miss a beat. It's actually already flowered!

Now to the Hoya experts: how long would you leave the plant in the 4" pot? Until I can't keep up with the watering schedule? It seems to like the clay pot but that makes it a little difficult to hang, and it's just about time to hang it.

I have a young start of the same Hoya, I'm a few months behind yours in growth. I would move it to a 6" hanging basket/pot before it gets much larger.

About six weeks ago I repotted from 4" to 6: pots a half dozen Hoya starts. they have really put on a lot of growth in the past month.

Well done with your Hoya curtisii ! But I would not move it too fast. Rather than a 6 in. pot try to find a 5 in. pot. Caution with H. curtisii, it WILL rot very easily if you even think about over watering it. Mine grows mounted but I am in Florida.

Hoya's are epiphytes and most prefer to be root bound. They all need a well drained mix. Over-potting into to large a pot is the fastest way to kill one. Move them up on pot size at a time.

Thank you! Yes, this plant really started taking off in the last few months. I think I'm going to try finding a good 5-6" plastic pot that won't hold too much water, so it can cascade like it wants to!

I have to say this is a very cool plant. I was originally searching for rosary vine, and when I got to the store, the lady really thought it was a rosary vine, and I wasn't sure. But it was so pretty, now I'm glad I drove so long to pick it up!

MJ- How do you have the curtisii mounted? Similar to a staghorn?

It's on a flat slated basket. Stuffed full of sphagnum moss then tied in with fishing line.
This is an old picture, (2012) Can't believe I haven't taken another one of it, I'll have to remedy that. Anyway it's climbed over both the front and back now and hangs down. Excellent drainage. I've found curtisii to be one of the easiest Hoya's to rot the roots on so I don't ever pot it, only grow it mounted.

That is sooooooo cool! I wish I could hang things outside all year long!

Well they don't stay out all year. From about November to mid March they go into the greenhouse. It's get's rather interesting at time fitting them all in.

Finally got around to taking a new pic of the H. curtisii. It's grow on both sides of the mount now.
