This is my Pachypodium but I am not sure what type. I have it at work as i live in missouri and it gets cold in Winter...the atmosphere here is better for her in the winter...in the summer i have it outside on my porch in full sun. Loved it this year and this would make one full year that i have had it. Bought at St. Louis Botanical gardens and wnat to know about the flower it shuld produce and what fertilizer to use..name brand and such. My e-mail is email@example.com . I also want to say you do have a lot of info here and just having trouble Id'ing this exact one amongst all of yours.
