Narcissus ‘King Alfred’ (Trumpet Daffodil)

Daffodil ‘King Alfred’ is one of the most famous and historically significant daffodil varieties in the gardening world. Introduced in the late 19th century, it became the standard for yellow trumpet daffodils and remains a symbol of classic spring beauty. With its bright yellow blooms and sturdy habit, this daffodil has captivated gardeners for over a century, although true ‘King Alfred’ bulbs are now rare.

Narcissus ‘King Alfred’ – Trumpet Daffodil: An In-depth Look

Daffodil ‘King Alfred’ is a classic trumpet daffodil known for its bright yellow flowers and robust growth habit. As a trumpet daffodil, it features a large, cylindrical trumpet (or corona) equal to or longer than its surrounding petals (perianth). The flowers are a vivid golden-yellow with slightly twisted petals that give the bloom a dynamic, wind-swept appearance. The iconic yellow trumpet is complemented by the flower’s slightly serrated, ruffled edges, which add texture and interest to the bloom. This daffodil blooms on strong, upright stems that hold the flowers high above the foliage, ensuring they stand out in garden displays.

Although ‘King Alfred’ was once the gold standard for yellow daffodils, its popularity has waned since the 1950s due to the introduction of newer varieties that offer larger flowers, better form, and enhanced performance. Today, finding true ‘King Alfred’ bulbs can be difficult, as many daffodils marketed under this name are look-alikes such as ‘Dutch Master‘, which are often sold with labels like “Improved King Alfred.”

Native:  Daffodil ‘King Alfred’ is a hybrid cultivar derived from the broader Narcissus genus, native to parts of Southern Europe and North Africa. Daffodils belong to the amaryllis family, Amaryllidaceae, which also includes snowdrops and amaryllis.

Plant Type and Habit:  This is a perennial bulb with an upright, sturdy stem that supports its large blooms. Each stem typically produces a single flower. As a perennial, it returns year after year, gradually multiplying to form a more substantial display over time.

Size: Typically grows 16-22 inches (40-55 cm) tall and about 3-6 inches (7-15 cm) wide, forming neat clumps that gradually expand as the bulbs naturalize.

Flowers: The flowers are large, measuring up to 4 inches (10 cm) across, and are a brilliant shade of golden yellow. The defining feature of this variety is its trumpet-shaped corona, which is long, cylindrical, and slightly flared at the edges. The ruffled rim of the trumpet adds texture and interest to the bloom, making it a standout among other daffodil varieties. The petals (perianth segments) are also bright yellow and slightly twisted, which gives the flower a lively, dynamic appearance. The petals and trumpet together create a striking contrast that draws attention to the daffodil’s classic, bold form.

Bloom Time: This daffodil blooms in mid-spring. Its flowers last for several weeks, providing a long-lasting display of color in the garden.

Foliage: The foliage is typical of daffodils, with long, narrow, strap-like leaves that are green and glossy.

Hardiness: This daffodil is a hardy perennial suitable for USDA zones 3-8. It thrives in cooler climates, where it can undergo a period of cold dormancy, which is essential for healthy blooming.

Uses: Daffodil ‘King Alfred’ is perfect for garden borders, mass planting, naturalizing in meadows or woodlands, and cut flowers. Its tall stems and golden-yellow blooms add height, color, and cheer while multiplying over time for an even more impressive display.

Toxicity: Daffodils are toxic to pets (including cats and dogs) and humans if ingested. Handling them may cause skin irritation in sensitive individuals due to calcium oxalate crystals in the plant’s sap.

Deer and Rabbits: Deer, rabbits, and other common garden pests tend to avoid daffodils due to their toxic properties.

Growing and Caring for Daffodil Flowers

Planting: Plant daffodil bulbs in the fall, 6-8 inches (15-20 cm) deep, and space them 3-6 inches (7-15 cm) apart in well-draining soil. Ensure the pointed end faces up and water thoroughly after planting. Learn how to grow daffodils like a pro and enjoy vibrant blooms year after year!

Light: Daffodils thrive in full sun but can tolerate partial shade. At least 6 hours of sunlight daily ensures healthy blooms.

Soil: Plant in well-draining soil with a slightly acidic to neutral pH (6.0-7.0). Avoid waterlogged areas to prevent bulb rot.

Watering: Water thoroughly after planting and maintain consistent moisture during the growing season. Reduce watering after blooming to allow the bulbs to dry out during dormancy.

Fertilizing: Apply a balanced fertilizer (10-10-10) when new growth appears in early spring. Avoid heavy feeding as it can lead to weak plants.

Pruning and Maintenance: Remove spent flower heads after blooming to prevent seed production, which diverts energy from the bulbs (unless you want your bulbs to naturalize). Allow the foliage to die back naturally after blooming. Do not cut it too early, as this nourishes the bulbs for the following year.

Propagation:  Propagate by removing offsets as the leaves fade in the summer.

Pests and Diseases: Daffodils are generally pest and disease resistant, but watch out for bulb rot in poorly drained soils.Slugs and snails may feed on shoots and leaves. They may be susceptible to the narcissus bulb fly, which lays its eggs on the bulbs. The larvae eat the inside of the bulbs, weakening or killing the plant.
