Are Green Onions Perennials? Learn How to Grow

Types Of Perennial Onions: Egyptian, Welsh, Chives, And More

Perennial onions, also known as perennial scallions or green onions, are a versatile and reliable addition to any garden. They belong to the Allium family and come in various types, each with its unique characteristics and flavors. Some of the most popular perennial onions include Egyptian onions, Welsh onions, chives, leeks, potato onions, and ramps.

Egyptian onions, also known as Egyptian walking onions, are fascinating plants that reproduce by forming small bulbils on the top of their stalks. These bulbils fall off and sprout in new spots, giving the plant its “walking” name. Egyptian onions have a pungent flavor and are often used in cooking.

Welsh onions, on the other hand, are known for their tender leaves and stalks. They do not develop large bulbs like other onions, but their mild and slightly tangy flavor makes them a favorite in culinary dishes.

Chives, which are widely used as a garnish or in soups and salads, have thin and grass-like leaves. They produce beautiful pink flowers that are not only attractive but also edible. Chives have a mild onion flavor and add a pop of color to any dish.

Leeks are another type of perennial onion that can be grown in your garden. They are typically started from seeds or seedlings and are allowed to overwinter. Leeks develop small bulbs around the mother plant, and their mild flavor is delicious in soups and stews.

Potato onions are reliable and easy to grow. They produce larger bulbs that can be used for cooking, while the smaller bulbs can be replanted for future harvests. Potato onions have a slightly sweet and milder flavor than traditional onions.

Ramps, a native plant to North America, are highly sought after for their savory flavor. However, they take several years to reach a harvestable size. Ramps can be grown from seeds, bulbs sourced online, or by replanting from a farmers market in the spring. >It’s important to note that large clumps of wild ramps should not be dug up and moved to the garden to preserve their natural populations.

Growing Perennial Onions: Care And Maintenance

One of the great advantages of perennial onions is their low-maintenance nature. However, like any plant, they do require some care to thrive.

Most perennial onions prefer full sun and well-draining soil. However, ramps are an exception and thrive in shady conditions. You can plant them in raised beds, herb gardens, or flower borders, depending on the specific needs of the onion variety.

Regular weeding is essential to keep unwanted plants from competing with perennial onions for nutrients and space. Using straw mulch can help reduce weeds and retain soil moisture, especially in dry climates.

Perennial onions appreciate deep watering, especially during hot and dry weather. Ensure the soil is moist but not waterlogged. To help retain moisture, you can add a layer of mulch around the plants.

Egyptian onions, in particular, benefit from regular weeding and occasional watering. Their bulbils settle and grow quickly when given these simple care tasks. Applying a top-dressing of compost and organic fertilizer annually can also greatly enhance their growth.

Welsh onion plants take 2 to 3 years to size up and divide. During this time, regular weeding, deep watering, and top-dressing with compost are necessary. Welsh onions bloom in mid-summer and attract pollinators like bees. Trimming off fading flower stalks or leaving them to go to seed helps thicken the clumps.

Potato onions are relatively low-maintenance but may require division if the bed becomes overcrowded. An annual top-dressing of compost is recommended to provide nutrients for healthy growth. Moving the plants to a new bed and practicing crop rotation can also help reduce pest and disease problems.

Chives are extremely easy to grow and require little care once established. Applying compost and cutting back the plants after blooming promotes fresh growth. Consistent watering, especially in hot weather, is important to keep the plants healthy.

Leeks need consistent watering, particularly during the summer months. Regular deep watering helps ensure that the plants develop properly. Blanching leeks using hilling or a cardboard collar increases the edible portion of the leek, making them more desirable for culinary use. Adding compost to the beds in the spring provides essential nutrients for healthy growth.

Harvesting Perennial Onions: Methods And Techniques

Harvesting Perennial Onions

Knowing when and how to harvest your perennial onions is crucial to ensure the best quality and flavor from your plants. Here are some guidelines for harvesting different types of perennial onions:

1. Ramps: Ramps are highly prized for their delicate flavor, but they take several years to establish and reach a harvestable size. During this time, it’s essential to remove weeds and add compost or chopped leaves to the soil for optimal nutrient availability.

2. Egyptian onions: Harvest Egyptian onions by either cutting off the hollow leaves or cutting the entire stem. The bulbils that form on the stalks can be eaten raw or pickled, adding a unique flavor. Harvesting the bulbils also helps redistribute energy for better growth.

3. Welsh onions: Welsh onions can be dug up as soon as they are large enough to be harvested. Any extras can be tucked back into the soil for future propagation. The beauty of Welsh onions lies in their ability to be continuously harvested without harming the plant.

4. Potato onions: Potato onions can be used as needed throughout the growing season. They can be pulled up individually or harvested in late summer when the entire crop is ready. Simply dig up the cluster of bulbs and brush off any excess soil.

5. Chives: Chives can be harvested by pinching out individual stems or by cutting bundles of leaves. Regular harvesting encourages new growth and prevents overcrowding.

6. Leeks: Harvest leeks in autumn and winter as needed. Gently dig them up using a garden fork, being careful not to damage the roots. It’s advisable to leave about half of the plants in the ground to regrow for the next season.

These guidelines will help you maximize the flavor and quality of your perennial onions. Remember to care for your plants by providing proper nutrients and removing competitive weeds. Enjoy the bountiful harvest!

Fertilizing And Composting Perennial Onions: Tips For Healthy Growth

Frequently Asked Questions

Which onions are perennial?

Perennial onions are a diverse group, encompassing varieties such as Egyptian walking onions, Welsh onions, and chives, each with their own distinct edible parts. Egyptian walking onions are particularly notable as they have edible bulbs and foliage, making them a versatile and enduring choice. Similarly, Welsh onions offer tender leaves and stalks that can be consumed, adding a tasty dimension to various dishes. Chives, on the other hand, not only yield a bountiful harvest of grassy leaves but also produce beautiful edible pink flowers, bringing both flavor and aesthetic appeal to any culinary creation.

Will green onions keep growing back?

Yes, green onions have the amazing ability to regrow quickly after being cut. Once you trim off what you need, the onions will sprout new growth almost magically. It’s fascinating to witness the regrowth of green onions, as they can shoot up overnight, providing you with a continuous supply of fresh green onions for your cooking needs.

Can you leave green onions in the ground over winter?

Yes, green onions can be left in the ground over winter in USDA zones 6 through 9, where the winters are mild. For those in colder areas, overwintering green onions is possible. Once the ground freezes in fall, it is recommended to protect the bulbs by covering them with a thick layer of mulch. This will help insulate the onions and ensure their survival during the winter months.

How do green onions reproduce?

Green onions reproduce through a process called vegetative propagation, similar to how onions and garlic reproduce. Green onions, also known as scallions or spring onions, develop a cluster of bulbs at the base of their stems. These bulbs contain the necessary nutrients for growth and can sprout into new plants. As the green onion plant matures, these bulbs enlarge and eventually develop shoots, allowing for the production of new green onion plants.

This asexual method of reproduction allows green onions to easily propagate and produce new plants without the need for seeds. By utilizing their bulbous structure, green onions can regenerate and continue their lifecycle, ensuring a consistent supply of these flavorful vegetables for our plates.
