Description
For horticultural purposes, daffodils are split into 13 divisions. All are of garden origin, except for Division 13 species.
Division 4 – Double cultivars – Each stem has one or more flowers, with doubling of the perianth segments or the corona or both. Some are sweetly scented. Usually mid and late season flowering. They are less popular than many other types because they tend to be late flowering, and buds will not open properly if they have undergone dry conditions while developing.
Hardy to Zones 3-9. Plant in fall, 4-6″ deep in rich, well drained soil. They enjoy full sun in cool areas, and some shade in warmer areas. Water well during growth and allow to dry out once the leaves die down. Remove spent flowers. Apply a low nitrogen, high potash fertilizer after flowering if bulbs are not performing well.
Prone to narcissus bulb fly, bulb scale mite, narcissus nematode, slugs, narcissus basal rot, narcissus yellow stripe and other viruses and fungal infections.
