Aloha. My Cactipes flowered & am fortunate to have a seed pod developing. How do you harvest? Storing? When does it open? This is a first for me.
This site may help... careful as they are poisonous plants... though it is also used as a medicinal, however you should research that first.... http://zipcodezoo.com/Plants/P/Pachypodium_cactipes/
At the top of the main list of threads, there is one called "Resources on the Web". There is a web link for Arid Lands. They are a reliable source for that information. I know that they have a group overseas collecting plants and seeds right now. Perhaps some of their nursery staff could help you, though. Give them a call. Mark
