Onions are a widely cultivated vegetable all around the world, used in cooking for their distinctive flavor and nutritional benefits. Onion plants belong to the Allium family, which also includes garlic, leeks, and chives. However, onions differ in their growth requirements based on the variety and the hours of daylight they need to grow properly. In this article, we will explore what are short-day onions and how they differ from long-day varieties. We will also discuss the benefits of planting short-day onions and some of the most popular short-day onion varieties.
Understanding Short-Day and Long-Day Onions
Onion plants are categorized into two groups based on the hours of daylight they need to grow properly. These groups are known as short-day onions and long-day onions.
- Short-Day Onions: Short-day onion varieties require around 12 hours of daylight to form bulbs, which typically occur during the fall and winter months.
- Long-Day Onions: Long-day onion varieties require around 14-16 hours of daylight to form bulbs, which typically occur during the spring and summer months.
The hours of daylight required for proper onion growth vary depending on the onion variety and the location where they are planted.

Benefits of Planting Short-Day Onions
Planting short-day onions has several benefits, including:
- Early Harvest: Short-day onions are usually ready for harvest earlier than long-day onions, making them a great choice for gardeners who want to get an early start on the growing season.
- Suitable for Most Regions: Short-day onions are ideal for planting in areas with mild winters and early springs, as they require fewer hours of daylight to form bulbs.
- Less Susceptible to Bolting: Short-day onions are less likely to bolt, which means they are less likely to prematurely send up a flower stalk and reduce the size and quality of the bulb.
Popular Short-Day Onion Varieties
Some of the most popular short-day onion varieties include:
- Red Creole: This onion variety is known for its red skin and spicy flavor. It is a popular choice for southern gardeners and is often used in Cajun and Creole dishes.
