Kniphofia rooperi flowers here in September-October. Perhaps different 
populations flower at different times.

Identification of red-hot pokers is notoriously difficult, even in the wild, 
and I would be cautious about accepting the name on a label, and even less 
on seeds in a packet.

I continue to be fascinated by how climate affects flowering time.
Kniphofia rooperi flowers here from August-October.
