We killed Sprekelia for years until I discovered that it likes hot, 
baking sun.  Our clumps multiply so fast now, that they must be divided 
every few years.  FYI, in the past 6 years, we have only dropped to 8 
degrees F, with our last 0 degree F winter in 1996.  During this same 
6-year period, we had no luck overwintering x Hippeastrealia 'Durga 
Pradhan' in many different locations, but when we grew seedlings from 
this, we had had 100% surivability for 4 years, with a low temperature 
of 8 degrees F.   This includes 1-year old seedlings in the ground with 
no winter protection.  I have also had 100% survival from x 
Hippeastrealia 'Red Beauty', surviving the same temperatures mentioned
