My adenium seeds (thanks Rucky!) are in. You all could have warned me that harvesting the seed from within the covering/sheath was not unlike pinching a zit!
I only broke out half the seeds. They are planted in some rich volcanic sand acquired from my recent travels, perlite and cactus soil. On top is only 1/8" thick. I have them in the shade and will be watering them from the bottom. Do I need to cover them in plastic? Houston temps at night will drop to 60"s. But the day will be upper 80's-low 90's. I will be leaving town again soon. I hope to have some sprouts when I return!
