How to Grow
Planting Narcissus ‘Sun Disc’ bulbs should occur in the early to mid-fall while the soil is still workable. Select a site offering full sun to light part shade; ensure any shade provided is located behind the planting, as these flowers naturally orient toward the sun. Cultivate the soil to be organically rich loam and ensure excellent drainage, as poor drainage is the primary cause of bulb rot. Set the bulb 2 to 3 times as deep as the bulb is tall, typically 3-6 inches below the soil surface, spacing them 4 to 10 inches apart.
During the spring growing season, maintain medium soil moisture, ensuring the soil stays uniformly moist while the foliage develops and flowers mature. While Narcissus ‘Sun Disc’ is notably drought tolerant once dormant, consistent moisture aids bulb rejuvenation. After the flowers fade, resist the urge to cut the foliage prematurely. Allow the leaves to yellow completely, which enables the bulb to store energy for the next season’s display.
Maintenance is generally easy. After blooming, you may deadhead spent flowers by removing the stem tops to prevent seed formation, which diverts energy from the bulb. These daffodils can be left undisturbed for many years. If you notice a decline in bloom quality or quantity, divide the clumps immediately after the foliage fully dies back.
Landscape Uses
The Jonquilla daffodil excels when allowed to naturalize, which perfectly suits the suggested use for Narcissus ‘Sun Disc’. Instead of isolated plantings, aim for drifts of at least six bulbs, or preferably large, sweeping masses that mimic natural spread. This creates a far more impactful display than smaller, regimented groupings.
These miniature spring stars fit beautifully in beds, borders, and especially in wild gardens or under deciduous trees where they receive full sun before the canopy leafs out. They look wonderful mixed with other spring ephemerals like grape hyacinths or early tulips, providing excellent textural contrast due to their finer leaves. Allow Narcissus ‘Sun Disc’ to colonize beneath shrubs for a cheerful, effortless groundcover effect.

Noteworthy Characteristics
Narcissus is a genus of about 50 species of bulbous perennials from Europe and North Africa, serving as a fundamental mainstay of the spring garden. Cultivated daffodils are organized into 13 divisions based on bloom characteristics, with ‘Sun Disc’ being a member of Division 7. Narcissus ‘Sun Disc’ is a fragrant, dwarf, late-flowering Jonquilla daffodil showing rounded, 1-2 inch flowers with bright yellow petals surrounding a distinctive darker yellow, fringed, disk-shaped cup.

Potential Problems
Daffodils, generally, are noted for being remarkably pest-free when sited in well-drained, healthy soil; bulb rot is the main issue arising from overly saturated conditions. The primary cultural hazard is failing to provide sharp drainage, leading to fungal issues. Infrequent pests may include slugs, snails, or the specific narcissus bulb fly.
While Narcissus ‘Sun Disc’ resists nibbling pests like deer and rabbits, be vigilant for signs of the Narcissus yellow stripe virus, for which there is no cure—always remove infected plants immediately. Managing pests centers on good site selection and cultural care rather than chemical intervention.

Ensure you plant your Narcissus ‘Sun Disc’ bulbs in well-draining soil during the autumn months for a stunning spring return.
Companion Planting for Spring Displays
When planning spring beds alongside Narcissus ‘Sun Disc’, consider partners that share similar cultural needs regarding sun and moisture. Since daffodils naturalize and their foliage dies back slowly, choose companions whose spring foliage emerges slightly later or whose growth habit can conceal the untidy daffodil leaves. Plants like late-emerging perennial Geraniums or early blooming Alliums that bloom slightly later pair well.
Avoid locating Narcissus ‘Sun Disc’ directly next to species that require consistently moist soil well into summer, as the bulbs need a dry period during summer dormancy. Areas where early blooming low-growing perennials emerge after the daffodil blooms fade create seamless seasonal transitions, enhancing the border design.
Seasonal Care Calendar
Spring care focuses primarily on observation; after the golden yellow flowers finish, remove the spent stems but leave all foliage intact until it yellows naturally, usually late spring or early summer. Minimal intervention is required during the summer dormancy period, provided the soil is not waterlogged over winter.
In early fall, this is the ideal time to plant new bulbs or lift and divide established clumps of Narcissus ‘Sun Disc’ if they have become overcrowded, which maximizes bloom size for the following spring. Avoid high-nitrogen fertilization in the fall, as this encourages soft leaf growth rather than robust bulb development for the next season.
