Winterflowering Kniphofias

I have now done what I should have done earlier & got out the Flora of 
Southern Africa part covering Kniphofia (Codd 2005) (which is essentially 
and disappointingly the same as Codd's 1968 work on the genus).

It says that K. rooperi 'can usually be recognized by the large globose 
racemes which appear mainly during winter and spring' and that it comes from 
marshy places near the coast of the Eastern Cape and southern Natal 
(including around my parents-in-law's area, which makes a visit more 
alluring). Codd also records intermediates between K. rooperi and K. uvaria 
(and possibly K. citrina) from further inland. This all makes me wonder if 
the clone I grow (of garden origin) is indeed true K. rooperi.

Tony, Lauw and Ellen: do your plants come from known wild provenances?

As John and Ellen confirm, this must have something to o with   region of
origin of the various populations.  The same cause of the difference in
flowering period was noted for Gladiolus dalenii.
