Narcissus pseudonarcissus , from the genus Narcissus , are harbingers of spring ; their horn - shaped flowers in shades of yellowed or white grow from bulb . Narcissus pseudonarcissus are perennials that return year after year in the garden when given the proper civilization . American gardener growdaffodilsacross most of the temperate - mood states .

Life Cycle

The key to a daffodil ’s sprightliness is the wellness of the underground bulb . The bulb is a modified stem that stores sugar . From the bulb base , fragile roots develop to absorb weewee and nutrient . Inside the bulb are layer of tissue , including cell that develop into flower bud and leaves . The electric-light bulb remain year after class . Cool grime temperature in wintertime trigger endocrine to form a preliminary flower bud . In late wintertime ’s passion , the bud and leaves emerge from the soil . The efflorescence endure one to three weeks , but the leaves endure into late spring . The foliation transmit photosynthesis to refill the bulb with food for thought so it can produce side bulbs and bloom again next spring .

Growing Requirements

daffodil grow best when planted in a moist but well - drained stain . avert planting them in pack together or heavy soils that readily flood or persist pie-eyed for long period after rain . Bulbs moulder in O - depleted ground . Ideally , when daffodil bulbs are torpid in summertime , warm and dry filth is better than coolheaded , wet conditions . works daffodils where the foliage basks in no less than 6 hr of sunlight day by day . Without sufficient brightness level , the leaves can not replenish the energy stockpile of the bulbs . Weak , malnourished bulbs neglect to return another year .

Regional Considerations

In a broad linguistic context , daffodil mature well in U.S. Department of Agriculture plant hardiness zones 3b through 9a . However , not all species or cultivars of Narcissus pseudonarcissus do well in regions with climatic extreme , such as winter common cold in zone 3 and 4 or summer heat in zone 9 . In these areas , only some daffodils grow as perennials . In Minnesota , in zones 3b and 4 , only the hardiest daffodil survive the foresighted , cold wintertime and cool , moist soils in summertime . Conversely , the long , hot summer in northern and central Florida , zone 9 , can harm some daffodils since the estrus make foliage to prematurely shrivel up or summertime rains can lead to bulb rot .

Special Characteristics

Narcissus pseudonarcissus stop toxins that preclude rodents and deer from eating the electric-light bulb , flowers and leaf . Therefore , the plants tend to raise without any vulture . As long as leave make food after flower ends and naturally shrivel away by late spring , daffodil tend to naturalize . Naturalizing means that the bulbs reproduce and that seed occasionally forms . This allows plants to multiply in number and physically scatter across a landscape . For example , if you imbed 10 daffodil bulbs on a cheery hillside , you should expect to see three to five times as many bulb and springtime flowers within five years .
