An onion plant is characterized by its unique structure, featuring both foliage and a flowering stalk.
Onion Plant Appearance
Here’s a breakdown of what an onion plant looks like:
Leaves
- While the reference does not go into detail about the leaves, they are typically tubular, hollow, and green, emerging from the base of the bulb. These leaves are the plant's primary source of photosynthesis before the flower stalk emerges.
Flower Stalks
- The common onion develops one or more leafless flower stalks that are central to its reproductive process.
- These stalks can grow quite tall, ranging from 75–180 cm (2.5–6 feet) in height.
Flowers
- At the top of the flower stalk, you will find a spherical cluster of small, greenish-white flowers.
- These flower clusters are a distinctive feature of the onion plant, appearing as a ball of tiny blooms.
Bulbils
- Some flower clusters also produce bulbils, which are essentially tiny secondary bulbs.
- These bulbils are a means of asexual propagation and can be used to grow new onion plants.
