The plant known as Asparagus officinalis grows to heights of up to two meters in its natural state. Its stems are stout and branch out into feathery foliage that resembles needles. These needle-like structures are technically cladodes which measure between 6 and 15 millimeters long.
The English word asparagus derives directly from classical Latin sources while earlier centuries used the name sperage taken from Medieval Latin sparagus. An eleventh-century text records the appearance of the word sparagus in written English before peasants referred to it as sparrow grass during this period.
World production reached 8.6 million tonnes in 2023 with China accounting for 87 percent of the total harvest. Regions like the west coast of North America offer ideal conditions for cultivation due to soils too saline for normal weeds to grow.
Asparagusic acid breaks down during digestion into volatile sulfur-containing compounds including methanethiol dimethyl sulfide and dimethyl disulfide among others. Estimates show 40 to 79 percent of people excrete odorous urine after eating asparagus with onset occurring rapidly between 15 to 30 minutes after ingestion.
European settlers brought seeds to North America by 1655 while William Penn advertised crops suitable for Pennsylvania climate in 1685 including asparagus. Monasteries cultivated the crop by 1469 while English farmers adopted it around 1538 and German cultivation began shortly after in 1542.
