The daffodil-flowered leek or daffodil leek ( Allium narcissiflorum ) is a species of the genus leek ( Allium ).
features
The daffodil-flowered leek is a perennial herbaceous plant that usually reaches heights of 15 to 35, rarely up to 50 cm. Elongated onions sit on the short “rootstock”. The onion skins are brownish in color, have reticulate fibers and remain on the onion as a tuft of fibers up to 5.5 cm long. The stem is erect, green, almost round, compressed in the upper part and has two edges. The plant has 3 to 5 green, bare, linear, flat leaves.
Up to eight flowers are grouped into a golden inflorescence, which is initially nodding and later upright. The bilobed bract is shorter than the inflorescence and persistent. The hermaphroditic, threefold flowers are bell-shaped. There are 2 circles, each with three purple-pink bracts , the inner ones being somewhat wider and blunt. The six stamens are shorter than the inflorescence. The scar is three-lobed. The flowering period extends from July to August.
