Answer: Thank you for asking but Monrovia is a wholesale only nursery and does not sell plants or seeds retail by mail order or by web site -- and Baobab (Adansonia digitata) is not included in Monrovia's plant list in any case. This is a very unusual plant and I doubt you will be able to find an exact replacement, especially on short notice.
I doubt it has received too much heat, this plant is native to the savannas of Africa so it is well acclimated to heat and drought both. Unfortunately, I have never grown one of these as a container plant. It is possible that it may have been overwatered, or it might be beginning to show signs of seasonal change since it is deciduous.
I would strongly suggest you contact the owner and allow him to help you troubleshoot as he will be familiar with its normal growth cycles.
Otherwise you might try contacting some of the botanical gardens near you, Missouri Botanical Garden for instance should be a good resource.
I'm really sorry you are having this problem. I hope it is okay. Good luck!
