Daffodil 'Telamonius Plenus' Narcissus 'Telamonius Plenus' (4)

Water

The Double Daffodil, also known as Narcissus 'Telamonius Plenus,' should be watered deeply and thoroughly to ensure the water reaches the roots. During the growing season, water the plant when the top inch of the soil feels dry, typically about once a week, depending on weather conditions and soil type. Aim to provide about one gallon of water per plant each week, adjusting for rainfall. It is critical not to overwater, as this can lead to bulb rot. Decrease watering once the flowers have faded and the leaves begin to yellow, indicating the plant is entering dormancy.

Light

The Double Daffodil thrives in full sun to partial shade. The ideal spot for this plant is an area that receives at least six hours of direct sunlight each day, though it can tolerate some light afternoon shade. Avoid deeply shaded areas, as too little light can impede flowering.

Temperature

The Double Daffodil prefers a temperate climate and can survive in temperatures ranging from approximately 50°F to 70°F. While it can tolerate cold down to about 20°F after it is well-established, temperatures below this threshold can harm the plant. The ideal temperature range for active growth and flowering is between 50°F and 65°F.

Pruning

Pruning the Double Daffodil involves deadheading the spent flowers to encourage future blooms and to keep the plant looking tidy. Once the flowers have faded, cut the flower stalks back to the base, but leave the foliage in place. The leaves should be allowed to die back naturally to feed the bulbs for next year's growth. Prune the Double Daffodil once the blooming period is over, typically in late spring.

Cleaning

As needed

Soil

Double Daffodil prefers well-draining soil rich in organic matter with a pH of 6.0 to 7.0; a mix of two-thirds loam and one-third aged compost or well-rotted manure is ideal.

Repotting

Double Daffodils typically do not need repotting as they grow from bulbs; divide clumps every 3-5 years to maintain vigor.

Humidity & Misting

Double Daffodil tolerates average outdoor humidity; specific humidity levels are not crucial for its growth.

Suitable locations

• Indoor

  Ensure bright light, cool temps, and pot with drainage.

• Outdoor

  Plant in autumn, full sun to partial shade.

• Hardiness zone

  3-9 USDA

Life cycle

Narcissus 'Telamonius Plenus', more commonly known as the double daffodil, begins its life cycle as a bulb planted in the fall before the first frost. The bulb enters a dormancy period over the winter, conserving energy and awaiting optimal growing conditions. With the arrival of spring, the bulb awakens and sprouts, sending up green shoots and leaves that harness sunlight through photosynthesis. Following the development of foliage, flower buds emerge and bloom into the plant's characteristic full double flowers, which are bright yellow and fragrant. After flowering, the plant enters a period of senescence; the leaves yellow and die back as the plant redirects energy to the bulb, which matures and may divide to produce offsets. These new bulbs, or offsets, can be separated and planted to start new plants, while the original bulb enters another dormancy cycle until the next growing season.

Propogation

  Spring-Early Summer

• The most popular method of propagation for the Daffodil 'Telamonius Plenus' is by dividing its bulbs, typically after the foliage has died back in late summer to fall. To do so, carefully dig around the plant with a garden fork, being cautious not to damage the bulbs. Gently lift the clump of bulbs from the ground and brush off any excess soil. You'll find that the bulbs have naturally multiplied over the growing season, forming offsets known as "bulbils." These bulbils can be gently pulled apart from the mother bulb. Replant them immediately, at a depth three times the height of the bulb, which is typically about 6 inches (15 centimeters), ensuring they have adequate space to grow. This straightforward process allows for a cost-effective method to expand your Daffodil 'Telamonius Plenus' collection or share with fellow gardeners.
