Narcissus (plant)
In gardens

While some wild narcissi are specific in terms of their ecological requirements, most garden varieties are relatively tolerant of soil conditions, however very wet soils and clay soils may benefit from the addition of sand to improve drainage. The optimum soil is a neutral to slightly acid pH of 6.5–7.0.

Bulbs offered for sale are referred to as either 'round' or 'double nose'. Round bulbs are circular in cross section and produce a single flower stem, while double nose bulbs have more than one bulb stem attached at the base and produce two or more flower stems, but bulbs with more than two stems are unusual. Planted narcissi bulbs produce daughter bulbs in the axil of the bulb scales, leading to the dying off the exterior scales. To prevent planted bulbs forming more and more small bulbs, they can be dug up every 5–7 years, and the daughters separated and replanted separately, provided that a piece of the basal plate, where the rootlets are formed, is preserved. For daffodils to flower at the end of the winter or early spring, bulbs are planted in autumn (September–November). This plant does well in ordinary soil but flourishes best in rich soil. Daffodils like the sun but also accept partial shade exposure.

Narcissi are well suited for planting under small thickets of trees, where they can be grouped as 6–12 bulbs. They also grow well in perennial borders, especially in association with day lilies which begin to form their leaves as the narcissi flowers are fading. A number of wild species and hybrids such as "Dutch Master", "Golden Harvest", "Carlton", "Kings Court" and "Yellow Sun" naturalise well in lawns, but it is important not to mow the lawn till the leaves start to fade, since they are essential for nourishing the bulb for the next flowering season. Blue Scilla and Muscari which also naturalise well in lawns and flower at the same time as narcissus, make an attractive contrast to the yellow flowers of the latter. Unlike tulips, narcissi bulbs are not attractive to rodents and are sometimes planted near tree roots in orchards to protect them.
