Thanks Baja!
But, I can’t take full credit for growing them indoors, all my plants spend the Summer outside here in NJ. Our deck is fully “loaded” with all sorts of C&S, with emphasis on Caudiciforms and Epiphyllums, Stapeliads etc. By September they always go back inside in front of bright windows. I am doing this for many years, I just realized that my Pachypodium densiflorum is going on for ca 35 years.
Crazy!!
