====Vegetative==== ; Bulbs : The pale brown-skinned [[ovoid]] [[tunica (biology)|tunicate]] [[bulb|bulbs]] have a membranous tunic and a corky stem (base or basal) plate from which arise the [[adventitious#roots|adventitious]] [[root hair]]s in a ring around the edge, which grow up to 40 mm in length. Above the stem plate is the storage organ consisting of bulb scales, surrounding the previous flower stalk and the terminal [[bud]]. The scales are of two types, true storage organs and the bases of the foliage leaves. These have a thicker tip and a scar from where the leaf lamina became detached. The innermost leaf scale is semicircular, only partly enveloping the flower stalk (semisheathed). (see Hanks Fig 1.3). The bulb may contain a number of branched bulb units, each with two to three true scales and two to three leaf bases. Each bulb unit has a life of about four years.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1β29}}{{sfn|Okubo|Sochacki |2012|p=[https://books.google.com/books?id=5B-ucdbgA3wC&pg=PA104 104]}} Once the leaves die back in summer, the roots also wither. After some years, the roots shorten, pulling the bulbs deeper into the ground ([[Adventitious roots|contractile roots]]). The bulbs develop from the inside, pushing the older layers outwards which become brown and dry, forming an outer shell, the tunic or skin. Up to 60 layers have been counted in some wild species. While the plant appears dormant above the ground the flower stalk, which will start to grow in the following spring, develops within the bulb surrounded by two to three deciduous leaves and their sheaths. The flower stem lies in the [[axil]] of the second true leaf.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1β29}} ; Stems : The single leafless [[plant stem]] or scape, appearing from early to late spring depending on the species, bears from 1 to 20 blooms.<ref name=RHSAZ/> Stem shape depends on the species; some are highly compressed with a visible seam, while others are rounded. The stems are upright and located at the centre of the leaves. In a few species such as ''[[Narcissus hedraeanthus|N. hedraeanthus]]'' the stem is oblique. The stem is hollow in the upper portion but towards the bulb is more solid and filled with a spongy material.{{sfn|Straley|Utech|2003}} ; Leaves : ''Narcissus'' plants have one to several basal [[Leaf|leaves]] which are linear, ligulate or strap-shaped (long and narrow), sometimes [[Caespitose|channelled]] [[Acaulescent|adaxially]] to [[Leaf shape|semiterete]], and may (pedicellate) or may not (sessile) have a [[Petiole (botany)|petiole]] stalk.{{sfn|Kubitzki|1998|loc=[https://books.google.com/books?id=FyPVYzL76sMC&pg=PA100 Narcissus], pp. 100β101}} The leaves are flat and broad to cylindrical at the base and arise from the bulb.{{sfn|Sell|Murrell|1996|loc=[https://books.google.com/books?id=pKGlBap0FRYC&pg=PA285 Narcissus. p. 285]}} The emerging plant generally has two leaves, but the mature plant usually three, rarely four, and they are covered with a [[cutin]]-containing [[cuticle]], giving them a waxy appearance. Leaf colour is light green to blue-green. In the mature plant, the leaves extend higher than the flower stem, but in some species, the leaves are low-hanging. The leaf base is encased in a colorless sheath. After flowering, the leaves turn yellow and die back once the [[seed pod]] (fruit) is ripe.{{sfn|Hanks|2002|loc=[https://books.google.com/books?id=4_kH_BffGDgC&pg=PA1 Hanks, "The biology of ''Narcissus''"], pp. 1β29}} Jonquils usually have dark green, round, rush-like leaves.<ref>{{cite web |title=Narcissus jonquillan |work=Missouri Botanical Garden Plant Finder |url=http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=275814&isprofile=0&z=5 |access-date=July 6, 2018 |archive-url=https://web.archive.org/web/20180707005941/http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?taxonid=275814&isprofile=0&z=5 |archive-date=July 7, 2018 |url-status=live |df=mdy-all}}</ref>
