Try to aim for a seed spacing of at least
4.68 inches (12.0 cm) and sow at a depth of around
0.49 inches (1.25 cm). For optimal germination, soil temperature should be a minimum of
13°C / 55°F.
By our calculations, you should look at sowing Italian White about 21 days before your last frost date.
Italian White is half hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside.
The botanical epithet is from the Latin annuus meaning “annual”.
