 Perennial herb, up to 50cm high, native to Europe, naturalized and widely cultivated; leaves 3-5, glaucous; inflorescences 1-flowered, spathe pale brown; flowers fragrant, perianth white, perianth tube tapering abruptly to base, distinct portions of tepals erect to spreading, yellow, often twisted, oblanceolate, corona yellow, tubular, apex flared and ruffled. "Narcissus pseudonarcissus is the most variable species in the genus and includes many elements that sometimes have been recognized as separate species."

-Main volatiles found in the vacuum headspace concentrates of N.pseudonarcissus were (E)-ocimene (30%) and (Z)-ocimene (0.4%), (E,E)-alpha-farnesene (10%), 3,5-dimethoxytoluene (7%), and 1,4-dimethoxybenzene (5%). \\

+HS-SPME/GC/MS of homogenized Narcissus pseudonarcissus cv. ‘Ice Follies’ petals showed ocimene (20.2%), hexanal (9.4%), 3-hexene-1-ol (9.3%), δ-3-carene (7.1%), α-pinene (6.9%), myrcene (5.6%), limonene (2.7%), benzene (3.9%), and 4-ethyl-pyridine (3.9%) as main volatiles.

+Screening of Narcissus bulbs showed alkaloids present 0-0.927% (d.w.) with galanthamine 0-0.188% (d.w.). \\

+The main alkaloid of the bulbs, galanthamine, could be extracted from the plant matrix using supercritical fluid extraction (SFE) with supercritical CO2. 303 μg/g was the optimum galanthamine yield, other N. pseudonarcissus alkaloids such as O-methyllycorenine and haemanthamine were also obtained. \\
