A propos Hardy Plants

Hi all,

I'm trying to come up with a list of South African plants -- bulbs, 
succulents, shrubs, small trees -- that are hardy outdoors in central 
Indiana (USDA cold zone 5).

I have had no luck with Dierama -- they die every time I try to transplant 
or repot them.  Without fail!

Some African Gladiolus have survived for a time, like GG. oppositiflorus 
salmoneus (still going strong), G. dalenii (only one winter), G. 
x-gandavensis. How about G. saundersii?

The Crinum as mentioned recently.

Crocosmia as discussed several times.

A few Kniphofia have survived for a time in very protected spots.  One 
plant of K. northiae has survived several years in the raised bed rock 
garden, and even blooms occasionally.

Of course, what I really would like to see is a big tree-sized Aloe 
martholii or A. ferox here!  They were blooming while we were in South 
Africa in May and June.

Are there any large, succulent Euphorbia that are winter-hardy?

Can anyone give me anything concrete?
