Sun requirement for violet cauliflower: Plant in Full Sun
Cauliflower is a vegetable in the Brassicaceae family. The solid, firm head resembles that of broccoli and is usually white, but can also be yellow, purple, or green in color. Like broccoli, it sits atop a stalk. The head is wrapped in thick leaves that begin to open when the plant is ready for harvest. All cauliflower does best in cool weather.

What are growing degree days?
A plant grows with warmth, not with days. A growing degree day is one day's worth of useful warmth: how many degrees the day's average temperature is above the lowest temperature the crop grows at. Add them up from planting and you know how far along the crop is, whatever the calendar says.
Say that lowest temperature is 10°C. A day averaging 17°C gives 7 growing degree days. A day averaging 8°C gives none, as it is too cold for the crop to grow. That is why the same lettuce takes about 50 days in a summer and 90 in an autumn: it needs the same total warmth either way.
For violet cauliflower, the FAO EcoCrop database gives a lowest growing temperature of 5°C and a shortest growing cycle of 60 days at its best temperature, about 750 growing degree days to a first harvest.
Where you've told us where your garden is, we use this and the weather there to predict when your violet cauliflower will be ready to harvest. We don't use it for how long a plant lives or when it finishes: we go by what members have logged for that.
