14°C / 57°F to ensure good germination.
By our calculations, you should look at sowing Kaleidoscope about 35 days before your last frost date.
As Kaleidoscope is half hardy, ensure temperatures are mild enough to plant out (around 14°C / 57°F as a guideline) - wait until after your last frost date to be on the safe side.
