Sorry I had trouble with your spreadsheet but I am partially paralysed. I am a retired nurseryman with about 40 years growing experience with Amaryllids. I have lived on the west side of the Phoenix valley, plus I have a friend that has grown Belladonna in central Phoenix 20plus years. Summer temps are topped out around 125F,winter about20F. Here in the dry SW spring watering is critical for Amaryllids to flower not temp. Dormant bulbs heavily watered bloom in about 8 weeks.By heavy watering I mean weekly soaking. No rain for the past 8 months,we had several inches over the past 3 days. I would expect flowering later this year. Other bulb relatives like Habranthus will flower at 125F if they are watered every other day as will Rhodphiala and Crinums.Sprekelia bloom around oct no matter what the water pattern is.
