My Hoya pubicalyx “Red Buttons” seedlings now have their first real leaf. I will be transplanting them tomorrow, and will post photos soon. My H. heuschkeliana seed pod burst two days ago. I was able to plant around 15 seeds. It will be interesting to see what comes of these seedlings. The pod was on the yellow variety; but I keep both yellow and pink in the same pot. It would be neat if there was a cross of some kind. If the seeds are viable, it will probably take a year to make the determination.
