Large-Cup Daffodil is a herbaceous perennial bulb, a sterile hybrid formed from N. poeticus Γ N. pseudonarcissus that grows up to 1 foot, 4 inches tall. This plant has showy, fragrant flowers that bloom in early spring. The non-concolorous single flowers have a corona that is shorter than the petal length and flat leaves, both of which are distinguishing feature of the plant. Large-Cutp Daffodil does best sited in full sun or partial shade in moist, well-drained, organically rich soil. It is tolerant of heat and drought, but intolerant of extremely wet conditions. This plant benefits from the addition of bone meal or superphosphate to the planting hole. Plant 6 weeks before first freeze, 4-5" below the soil surface. Flowers tend to face the sun, so plant the bulbs where any shade will be to the rear of the planting. This plant has a spreading habit and is good for naturalizing. After the flowers have bloomed in spring, deadhead to prevent seed formation, but cut foliage back only after it has browned naturally. Insects, Diseases, and Other Plant Problems: This plant is pest and disease resistant due to its poisonous alkaloids content. Watch for slugs, snails and bulb mites. Bulb rot can occur in wet soils. Quick ID Hints: 1 flower to a stem Flowers are usually not concolorous Corona is shorter than the length of the perianth segments VIDEO Created by Elisabeth Meyer for "Edibles, Bulbs, and Houseplants", a plant identification course developed in partnership with Longwood Gardens.
