It doesn't look like any stem at all to me :-(

Yeah that's what I was afraid of :/

I thought maybe the little ring bit might have been something but no biggie. It was free and it can still look cute on a shelf. The main thing was not to get my hopes up. I'll keep looking out for a larger plant!

I posted this link on a similar thread from a few days ago. Not sure if it will work for Kerri, but it did work for Carnosa so..

It's a few comments down and posted by member "4C's Company, Inc". The comment refers to her mother's Carnosa that died and she salvaged one single leaf after all were lost. Her friend apparently advised her to snip 1/3 of the leaf (basicly the tip of the leaf) off. The wound sealed and later her leaf began to grow a stem from the petiole area.

The part in between the root ball the leaf isn't that part of the stem?

No, not if you mean the pic above. I believe it's part of the petiole connecting the leaf to the stem.

Sorry that link is no good, broken or doesn't go anywhere.

As a long time Hoya grower I will tell you it's one thing to root a Hoya leaf, it's altogether something else to get a new plant from it, happens extremely rarely, like maybe 10% of the time. I have personally stopped my own local supermarket from selling these individually potted leaves some yrs. ago (for $12 each) as they're a rip off since they'll never grow into an actual plant, sorry.

One of my kerriis got beat up by a hail storm this last spring, so I put a bunch of single leaves WITH a piece of stem in pots to produce new plants for next spring. I would keep the potted leaf because all it takes is a few cells of the stem to eventually start growing...

I bought a Hoya Kerri plant about 4 years ago - it was just a leaf in a pot (one of those Valentine's specials). The leaf remained the same for about 6 months. There was no sign of growth above the soil. I was eventually curious un-potted it and was surprised to see that it had a strong root system going. I then checked on the net and found info that you can only expect it to start showing signs of growth above soil level after about a year. I repotted it into a small clay pot and after about 6 months a small shoot appeared, which then grew steadily and at about 2 years it flowered for the first time. My plant is now about a metre long creeping up a wall, winding itself along a wire i had suspended to help it grow vertically. Maybe I was just lucky....I don't know. I did buy a second plant in its leaf cutting form about a year ago (this one was varieagted). It died after a few months!
