Narcissus ‘King Alfred’ short overview
Narcissus 'King Alfred' is a historic trumpet daffodil introduced in England in 1899 and still valued for its bold, vivid yellow flowers. Each sturdy stem carries one broad bloom with a long cylindrical corona, while narrow green leaves form a spring clump below. Plant bulbs in fall, about 4–6 inches deep, in moderately fertile, well-drained soil. Full sun gives the strongest flowering, though light partial shade is tolerated. Let foliage yellow naturally after bloom.
Taxonomic classification
Narcissus ‘King Alfred’ care guide
Light and placement
Give full sun for the strongest flowering, ideally with at least 6 hours of direct light. Light partial shade is acceptable, especially beneath deciduous trees that are bare during spring. Too little light produces weaker stems, fewer flowers and less reliable naturalizing. In hot regions, morning sun with light afternoon shade can reduce heat stress without significantly limiting bloom.
Watering and humidity
Water after fall planting and during dry periods while roots and foliage are developing. Keep soil evenly moist but never saturated through active growth and flowering. Reduce watering after the leaves yellow and the bulb enters summer dormancy. Outdoor humidity is normally sufficient; avoid irrigation that repeatedly wets dense foliage late in the season.
Soil and growing medium
Use moderately fertile, well-drained soil that retains some moisture during active growth. Loam is ideal, but the cultivar tolerates clay, sand, chalky soils and a range from acidic to alkaline conditions. Improve heavy clay with organic matter and avoid sites that stay waterlogged, since dormant bulbs are prone to rot in persistently wet ground.
Feeding
At planting, work a modest amount of bulb fertilizer or compost into poor soil without placing concentrated fertilizer directly against bulbs. After flowering, apply a balanced fertilizer while leaves are still green if soil fertility is low. Do not feed heavily with high nitrogen, and do not fertilize dormant bulbs in summer.
Growth and habit
Plants emerge from bulbs in late winter or spring, forming a tuft of leaves and upright flower stems. Established clumps can naturalize and gradually increase through offsets. For reliable flowering, allow the foliage to remain green after bloom so the bulb can rebuild reserves; avoid tying, mowing or cutting leaves prematurely.
Planting and repotting
Plant in fall, ideally from September through November in much of the United States, before the ground freezes. Set bulbs with the pointed end upward at roughly 4–6 inches deep, or about two to three times the bulb height, and space them about 4–6 inches apart. Water after planting and keep the site evenly moist during establishment.
Container-grown bulbs can remain in place for several seasons if flowering stays strong. Refresh crowded pots after the foliage has died back, separating offsets and replacing spent or poorly drained compost. Use a free-draining, moderately fertile container mix with drainage holes, and keep the bulbs cool and dormant over summer.
Propagation and pruning
Propagation
Propagate mainly by lifting clumps after the foliage fades and separating offsets. Replant offsets promptly or store them dry and cool until fall planting. Seed propagation is possible but slow and does not reproduce the named cultivar reliably; seedlings vary genetically and may take several years to flower.
Pruning
Remove spent flower heads after blooming if seed formation is not wanted. Leave all foliage intact until it has yellowed and detached naturally, then remove it neatly. Do not braid or cut green leaves, because premature removal reduces bulb recharge and can weaken flowering in the following year.
Overwintering
Leave bulbs outdoors in the ground in suitable USDA Zones 3–8, using well-drained soil and a light mulch in exposed or very cold sites. Container bulbs are more vulnerable to freezing; group pots against a sheltered wall or move them into an unheated garage after dormancy begins. Do not keep dormant bulbs warm and wet.
Uses
Use in spring borders, informal beds, lawns, woodland-edge plantings beneath deciduous trees, containers and cut-flower displays. It can naturalize and form drifts where drainage is good. Do not use any part as food or medicine; bulbs are toxic and should never be confused with edible onions.
Appearance
Narrow, strap-shaped green leaves emerge from the bulb in an erect to slightly spreading tuft. Each leafless stem carries a single broad yellow flower. The six perianth segments may be slightly twisted, while the central corona is cylindrical, yellow and distinctly flared or notched at the rim. These traits identify the cultivar within the classic trumpet-daffodil group.
Flowering
This Division 1 trumpet daffodil produces one flower per leafless stem. The trumpet, or corona, is at least as long as the surrounding perianth segments. In United States gardens it generally blooms in early to mid-spring, with timing shifting earlier in warm climates and later in colder regions. Removing faded flowers can direct energy away from seed production, but leaves should remain until they yellow.
Pollination and visitors
The open trumpet flowers may be visited by bees and bumblebees during spring, although this cultivar is primarily grown for ornament rather than as a major pollinator plant. Visitor activity depends on local weather, flower abundance and the availability of earlier or more rewarding nectar sources.

Diseases and pests
Diseases
Watch for narcissus basal rot, leaf scorch and daffodil viruses. Use healthy bulbs, avoid waterlogged soil, provide good air circulation and remove visibly diseased plants. Do not replant affected bulbs in the same location without addressing drainage and sanitation problems.
Pests
Slugs, narcissus bulb fly, narcissus eelworm and bulb scale mite may attack bulbs or foliage. Buy firm, disease-free bulbs, avoid overwatering and remove plant debris. Lift and discard badly damaged bulbs rather than composting them. Manage slugs with hand-picking, barriers or locally approved controls; chemical treatments are rarely needed for a healthy planting.
Toxicity and pollen
Narcissus bulbs and other plant parts contain toxic alkaloids and can cause gastrointestinal illness if eaten; the bulbs are especially dangerous because they may be mistaken for onions. Sap may irritate skin. Wear gloves when handling bulbs, keep them away from children and pets, and seek medical or veterinary advice after ingestion.
- Typical season
- Spring bloom period
- Pollination / pollen
- Heavy, insect-associated pollen; limited airborne dispersal
Daffodil pollen is generally heavy and released within the flower rather than dispersed in large airborne clouds. Allergy risk is usually low compared with strongly wind-pollinated plants, but sensitive individuals can still react to flowers, sap or handling. Cut stems may release sap that irritates skin.
Native habitat
This is a cultivated garden hybrid rather than a wild species with a single native habitat. Like other temperate Narcissus, it follows a seasonal bulb cycle: cool moist conditions support rooting and leaf growth, followed by spring flowering and a dry summer dormancy. It performs best in open, well-drained soils with winter moisture and summer rest.
Interesting fact
'King Alfred' was introduced in 1899 and became a standard yellow trumpet daffodil. The registered flower code is 1 Y-Y, meaning Division 1 with yellow perianth and yellow corona. It received the RHS First Class Certificate in 1899. The named cultivar is historically important, although newer trumpet cultivars often offer larger flowers or improved performance.
