Growing Non-GMO Large Cupped Carlton Daffodil Flower Bulbs

To ensure the best blooms, plant the bulbs in the fall, ideally before the first frost. The optimal planting depth is about 4-6 inches, and the bulbs should be spaced 3-6 inches apart to allow enough room for growth and air circulation. Daffodils need 12-16 weeks of cold in order to bloom in the spring. These daffodils prefer well-drained, moderately fertile soil. If your soil is heavy clay or particularly sandy, consider amending it with compost to improve its texture and fertility.

Carlton Daffodils thrive in full sun to partial shade. Full sun encourages the best flower production, but they can tolerate some shade, especially in warmer climates. Deadheading spent blooms is not necessary for reblooming but can improve the plant's appearance. To enhance perennial blooming power, allow the foliage to die back naturally after the blooms fade. This process enables the bulbs to store energy for the next season. Regularly applying a balanced, slow-release fertilizer in the fall can also promote healthy growth and robust blooming year after year.

Large Cupped Carlton Daffodil in the Flower Garden

Large Cupped Carlton Daffodils are particularly effective when mass-planted to create stunning swathes of bright yellow in early spring. Due to their moderate height (10-14 inches), they are best placed in the middle ground of a border rather than at the back. They can also be used in naturalized areas, under trees, or in rock gardens, where they can spread and multiply over the years to create a natural, effortless look.

Landscape Use of Large Cupped Carlton Daffodil

Carlton Daffodils are known for their strong, pleasant fragrance, which adds an extra sensory dimension to the garden. The scent is sweet and floral, making them excellent for cutting and bringing to enjoy in bouquets indoors.

These daffodils have been recognized for their performance and beauty. They have been awarded the Royal Horticultural Society's Award of Garden Merit, which signifies their excellence in garden performance, stability, and resilience.

According to the Royal Horticultural Society, there are approximately 13,000 distinct daffodil varieties. Carlton falls into the category of Large Cupped Daffodils, meaning that there is one flower per stem, with a cup-shaped corona of more than one-third but less than the length of the petals.
