Four o'clocks are not hardy perennials in my area, but one year a chain
store was selling the tubers in bags, along with bleeding hearts, daylilies,
and other tuberous rooted plants. All of the four-o-clocks that I bought
there survived the bagging and storage process and bloomed beautifully for
me that year. I'd guess that like most tuberous perennials, they'd be
happiest if transplanted while dormant - meaning late fall or early spring -
but that root is also a storage organ, so there's lots of "stuff" in there
ready to make new growth whenever. I'd agree with the posters who suggested
cutting back the top foliage.

I dug up some Four o clocks and moved them. They were at least 3 feet
tall,
and the root (rhizome, corm??) was good sized. (at least as big as a
woman's fist)
Of course the Four o clocks do not look happy in their new spot. Very
droopy and wilted looking. It's been a week since I transplanted them. I
am in South Louisiana, below New Orleans.
If they don't perk up, maybe just leave them in the ground and they will
catch up next season?
I did a Google search and the only transplant information that I could
find
was on seedlings.
