Beyond the bulb, onions hold a rich history and a flavorful presence in the kitchen. While their storied past is fascinating, their culinary uses are a true delight. For those who love cooking, onions offer a chance to share joy with loved ones. Whether you’re a seasoned chef or a kitchen novice, onions are a versatile ingredient waiting to be explored and savored.

According to various sources, onions have a rich history that spans thousands of years. The possible birthplace of onions is often attributed to the regions of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan.

However, some researchers suggest an alternative origin story, tracing onions back to Iran and West Pakistan.

Onions have been an important crop for thousands of years, with cultivation dating back over 7,000 years. Evidence of onion cultivation can be found in ancient civilizations such as Egypt, Greece, and Rome. While ancient Egypt made extensive use of onions, some historians believe that the Greeks and Romans introduced onions to Europe, who likely acquired the onion from the East in Central Asia.

Ayurvedic texts written by Charak Samhita (200 BCE – 300 AD) show onions were valued for healing. Yet, some considered onions and garlic ‘Tamasic’ and unhealthy, preferring ginger. Historically, India’s diet reflected this, with ginger dominating and onions/garlic being rare. The Mughal Empire (1526-1857) shifted this, making onions a staple. Now, modern research confirms onions’ benefits, echoing ancient wisdom – ancient meets modern!

Onions, particularly spring onions, have been a staple ingredient in Chinese cooking for centuries and are also valued in traditional medicine. Onion cultivation in China dates back to around 6000 BC, with onions being grown alongside other vegetables. This long history highlights the significance of onions in Chinese cuisine and culture.

Onion plants produce a flower cluster, or inflorescence, consisting of numerous small flowers.

In our last post, we explored the onion plant’s unique flowering process, where a tall, hollow stalk (scape) emerges from the center, topped with a conical bud enclosed in a protective spathe. Inside the bud, hundreds of tiny flowerets await their turn to bloom.

Slowly the onion’s protective spathe gives way as buds mature, bursting open to reveal the emerging inflorescence. Over 5-6 days, the buds unfurl, standing tall with the empty spathe providing base support (picture 4).

After a few days, the flowers begin to bloom, adding a vibrant touch to the plant.

The onion’s flower cluster, or umbel, is supported by a sturdy stalk called the peduncle or scape. This umbrella-like structure consists of tiny stalks (pedicels) holding hundreds of small flowers (florets), often over 200! The term ‘umbel’ originates from the Latin word ‘umbra’, meaning shade or shadow, reflecting its umbrella-like shape.

Each delicate flower on the inflorescence featured, 6 white petals with green stripes, 6 stamens (anther and filament), and a central pistil (stigma, style, and ovary), all supported by slender pedicels.

What Secrets Lie Within?

When I dissected an onion floret, I was amazed to find a three-celled ovary, each cell containing two ovules. This intricate design reveals the potential for seed production in each delicate flower.

Onion Floret’s Ovary. We didn’t notice the onion floret’s ovary had three cells until we dissected it. This tiny detail reveals the intricate design of the flower.

A. Initial bloom

B. Buds awaiting bloom

C. Full bloom

D. Gradual drying

Onion seeds are usually ready to harvest after the inflorescence dries out, which takes about two to three months.

However, we couldn’t wait that long and collected 2-3 inflorescences after a month. Despite the seeds being slightly damp and brown, we were thrilled to see them.

A month later, we collected the remaining flower clusters and gently crushed each floret to release mature black seeds, marking a successful seed harvest.

As I examined my onion plants, I was thrilled to notice the emergence of the first flower bud. This unexpected development sparked excitement, and I was eager to learn more.

The cone-shaped flower bud features a protective covering called a spathe, which safeguards the delicate florets inside. The spathe itself is white with numerous parallel green veins that converge at the tip.

The scape or peduncle is the stem that supports the onion flower. It grows from the terminal bud, characterized by its long, hollow, leafless structure with parallel veins, tapering towards the end, and lined with epidermal cells internally.

Onion plants typically produce flowers in their second growth phase, following the initial phase of development from seedlings to small bulbs, known as sets.

As days passed, our pot became a hub of activity, with many more scapes emerging alongside the leaves. At first glance, it was easy to confuse the two, but upon closer inspection, we noticed that the scapes were slightly thicker and with the distinctive flower buds perched on top.

We waited for almost two weeks for the buds to unfurl. The buds grew bigger and rounder, their skin becoming almost transparent, hence the floret buds are visible from outside.

Onion bulbing occurs when the plant’s energy shifts from leaf growth to bulb formation, storing excess food in the underground bulb, which we harvest as onions. Each leaf on the onion plant corresponds to a specific layer in the bulb, with the plant’s energy storing food in concentric rings as the leaves grow.

Both sunlight and temperature play significant roles in bulbing. When leaves receive sufficient sunlight, they produce food through photosynthesis, which is then transported to various parts of the plant. Excess food is stored at the base of the tubular leaves, contributing to bulb formation. Each green leaf produces food and stores excess in its corresponding sheath.

Planting onions no more than ½ to 1 inch deep allows for proper growth and development, which is why the soil often cracks as the bulbing process begins.

Onion bulb is covered by a few layers of papery skin/peel called tunic and so  it is also known as tunicated bulb.   These papery skin protects the bulb from drying as well as keeps them safe  from insects and germs.

The roots develop from the base of the new stem, distinguishing them from the older stem. Initially delicate and white, the roots increase in number over time, spreading horizontally to anchor the plant and absorb water and minerals.

When onion sets are planted, they often quickly establish themselves, producing new roots that spread horizontally. This helps the sets to anchor firmly in the soil and begin absorbing necessary nutrients and water for growth.

The green leaves of an onion plant are long, thin, and tubular, emerging from the base of the plant to form a sheath around the developing bulb. These leaves are typically a vibrant green color and play a crucial role in photosynthesis, supporting the growth and development of the onion bulb.

Let’s examine the pseudostem of an onion plant. Notice how green leaves emerge from the tightly wrapped tubular sheaths. Upon closer inspection, it’s evident that the green leaves appear to branch out directly from these sheaths, forming the pseudostem.

As the onion sprouts grow, the green leaf tissues and pigmentation become active. The veins of the tubular sheath diverge, leading to the base of the green leaf.  This is the first green leaf of a sprout

This enlarged picture reveals the interior side of same onion leaf as above, showcasing how veins in the tubular sheath diverge and connect to the green leaf’s base. The veins appear as light green lines within the white tubular sheath. Notably, a small, elongated portion of the white sheath extends above the green veins at the leaf’s base.

The exterior side of the tubular sheath displays green veins that seamlessly transition into the green leaf.

In contrast, the interior side shows the veins diverging to the right and left, meeting the base of the green leaf.

The interior side of a mature onion leaf is displayed flat, revealing parallel and diverging green veins from the tubular sheath. These veins form a silhouette with an elliptical shape at the center, tracing the base of the green leaf. The elongated white tubular sheath provides tight support, cradling incoming green leaves emerging from the center of the plant.

When we gently pressed the white sheath to flatten it, there was a slight tear on the white sheath but revealed the converging veins on the outer side, which became more prominent and seemed to trace the base of the green leaf.

1. A thin white membrane covers the interior.

2. The arrow indicates the hollow section, housing the leaf base.

3. After removing the membrane, the hollow leaf base is exposed.

4. A cross-section cut through the membrane and leaf reveals its hollow interior.

Onion leaves are characterized by their bluish-green color, hollow and curved shape with pointed tips, and a rounded outer surface with a flat inner surface.

They exhibit parallel venation, which supports their structure and facilitates the transport of nutrients and food materials to the onion bulb for storage.

When we open up an onion leaf, we could see the parallel venation more clearly and also see the inside lined with a protective epidermal peel.

The onion’s white tubular sheaths emerge from its stem, playing dual roles: forming the pseudostem to support green leaves for photosynthesis and storing excess food in the underground bulb for later use.

As new green leaves emerge, their tubular sheaths wrap tightly around the inner leaves, offering support and protection. This process is particularly visible in young sprouts, where the overlapping sheaths form a sturdy pseudostem.

In this way, each sheath holds the inner green leaves snugly, with each subsequent sheath growing slightly higher than the last. This layered structure allows the green leaves to emerge progressively higher, exposing them to sufficient light for photosynthesis and thus forming the pseudostem.

The veins of the tubular sheath seamlessly extend into the green leaf. When viewed from the outer side, the veins run parallel.

In contrast, the inner side shows a converging pattern, where the veins of the tubular sheath meet the green leaf, forming a flat surface. This arrangement allows for tightly packed green leaves.

The green leaf branches out from this point, while the tubular sheath continues to elongate a little, wrapping tightly around emerging inner leaves.

As each new leaf emerges, its tubular sheath wraps protectively around it, supporting the leaf during growth. This process repeats with each subsequent leaf, which creates elliptical holes or openings in the sheath as it pushes through. The result is the characteristic structure of the pseudostem.

The tubular sheaths possess flexible properties, allowing them to stretch and accommodate the plant’s growth. However, over time, the sheaths become increasingly thin and fragile, eventually succumbing to wear and tear.

Recall our last post, where we carefully separated the two sprouts and labeled them A and B? We highlighted the incredible potential of sprout B, showing its compact structure and remarkable growth capabilities, which make it a powerhouse in its own right.

Upon removing the last fleshy, white-purple layer, we discovered two small sprouts emerging once more.

We separated the two sprouts, labeling them A1 and A2, and presented them individually for clearer visualization.

To begin, we’ll carefully dissect the first tubular sheath.

The first leaf features a short green blade and a long tubular sheath, with a hole allowing the second, third, and fourth leaves to emerge. In contrast, these subsequent leaves have longer green blades but shorter tubular sheaths, roughly half the length of the first leaf’s sheath.

Notice the first green leaf: small and nestled within a tight white tubular sheath that encases longer inner leaves. Sprout A2 also showcases a new baby bud stem, giving rise to these leaves. This tiny stem contains axillary and terminal buds, essentially making it a mini plant.
