Variety traits

Plant height — Welsh onion

Allium fistulosum L.

An important morphological indicator that determines productivity, marketable maturity, and harvest convenience of the crop. It is measured from the soil level to the tip of the leaves or the flower stalk.

In the reference 10 varieties crop Welsh onion, where this is mentioned in the description.

For Welsh onion, the typical height of the leaf apparatus ranges from 25 to 60 cm, with the most vigorous forms potentially exceeding this figure. The height of the pseudo-stem, which influences the marketability of the "white leg," varies between 5–15 cm, while generative flower stalks reach 45–130 cm.

Plant height is closely related to green mass yield and technological aspects of harvesting. In green onion production, a leaf height of at least 30 cm is considered standard; however, excessive overgrowth can lead to tissue coarsening, and early bolting of tall flower stalks requires management to maintain product quality.
