Ask a Question forum: Is dormant period necessary for Amorphophallus?

Does anyone know what happen if Amorphophallus species do not get dormant in winter?
I know some tropical species (e.g. A. titanum) do not need dormant period to keep growing.
But many other species usually make their leaves only in spring, waking up from winter dormancy, and live only with the leaves in that season.

Actually I have some Amorphophallus in my green house and am wondering if I should withdraw them to cool atmosphere to let them go dormant.

Plants Admin Emeritus

My climate is very different than yours but I've brought plants inside over the winter. Some eventually go dormant while a few others continue to grow until mid spring and then go dormant. There are only a few truly evergreen species but a few others may occasionally skip the dormant period or have a very brief one. This is a very good article about Amorphs including dormancy.

Thanks for the comment, Evan
I will keep my ones in the green house this winter to see what happen.
