The rings of outer petals, or perianths, of their small blooms grow perpendicular to their cups, which are usually about half the length of the petals. Known for their strong fragrance, these delightful daffodils have enticed and enthralled gardeners since the 17th century. Three or more flowers grow on each stem of these reliable perennials, which return year after year in greater numbers. They provide magnificent drifts of colour when their bulbs are planted in large groups. They are great in beds and borders, near shrubs, beneath deciduous trees and in containers. Their beauty and scent make them wonderful in cut-flower arrangements.
