Description

Narcissus tazetta (the mountain ecotype) in Israel.

Narcissus tazetta is amongst the tallest of the narcissi, and can grow to a height of up to 80 cm,<ref name=Tazetta/> with thin, flat leaves up to 40 cm long and 15 mm wide. Umbels have as many as 8 flowers, white with a yellow corona.<ref>Linnaeus, Carl von. 1753. Species Plantarum 1: 290 Narcissus tazetta</ref><ref>Haworth, Adrian Hardy. 1819.

Ecology

Narcissus tazetta contains a fragrant compound found in only a few other plants, including roses and Acnistus arborescens, called orcinol dimethyl ether, which is almost undetectable to the human nose. Experiments with honeybees have shown they can readily detect it.<ref name="DudarevaPichersky2006">Template:Cite book</ref>

Distribution

Narcissus tazetta is a widespread species, native to the Mediterranean region from Portugal to Turkey and across the Middle East , Central Asia , Afghanistan, Pakistan, India, Nepal and Bhutan, as well as the Canary Islands, China (Fujian, Zhejiang) and Japan. It is also naturalized in Australia, Korea, Norfolk Island, New Zealand, Bermuda, Mexico and the United States (Oregon, California, Texas, Alabama, Arkansas, Florida, Louisiana, Mississippi, North Carolina, South Carolina and Virginia)<ref>Kew Checklist of Selected Plant Families</ref> and South America.<ref>Chile Flora</ref>

Uses

Narcissus tazetta is grown commercially for its essential oil, mostly in southern France. An interspecies hybrid, with Narcissus poeticus, is also grown for its essential oil. A recent medicinal use is that a certain protein known as lectin has antiviral properties against influenza. This is based on a dose-dependent manner. The antiviral property results from the fact that it can inhibit RSV during the viral infection cycle and so the problem could not spread. The antiviral activity of the certain lectin group protein will usually have a greater effect during the earlier stages of the influenza. It has little cytotoxicity and great potential as an antiviral agent, so it has potential for further use in biotechnology research in the future.<ref name="Groom1997">Template:Cite book</ref>
