Narcissus 'Thalia'

The triandrus daffodil (Narcissus 'Thalia') is a bulbous perennial plant with showy white trumpet-shaped flowers. Its petals are reflexed and twisted back, giving this daffodil a unique and elegant look. The pointed petals are lightly veined with a pale yellow band in the center. The bright green leaves have wavy margins and a narrow base. Blooms from February-April in full sun and sandy loamy soils. Depending on the region, this daffodil grows between 4-12 inches tall and makes an excellent cut flower. Triandrus daffodils prefer well-drained soils and moderate watering, making it a great choice for those gardens in drier regions.

watering

Triandrus daffodils (Narcissus 'Thalia') should be watered approximately once a week, although this may need to be adjusted depending on whether the plant is planted in a container or directly in the ground, and the soil type and local climate. As with any flowering plant, Triandrus daffodils require a generous amount of water for best growth and flowering.

sunlight

Triandrus daffodil, or Narcissus 'Thalia', does best in full sunlight, at least 6 to 8 hours of direct sunlight each day in order to properly grow and flower. The ideal times are between mid-morning and mid-afternoon when the sun is strongest. During periods of extreme heat, more shade may be necessary, particularly for young plants.

pruning

Triandrus daffodils (Narcissus 'Thalia') should be pruned once every 6 months following blooming, typically from April to August. When pruning a Triandrus daffodil plant, it is important to not cut off the green foliage as it is required for the following season’s flowers. Instead, you should gently remove the faded flowers at the base of the stem just above the green foliage. Additionally, removing any bulbs that have become overcrowded can help with the aeration of the soil and promote better flower growth. It is beneficial to fertilize with a balanced fertilizer after pruning, and then water thoroughly.
