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? John Grimshaw Dr John M.

The same cause of the difference in flowering period was noted for Gladiolus dalenii.
