Daffodils Sunny, yellow daffodils are a wonderful sign that spring has arrived! Plant the bulbs in the fall and they will bloom in late winter or early spring. Daffodils are hardy and easy perennials to grow in most areas in North America. The flowers have a central trumpet (corolla) — the length varies among cultivars — surrounded by a collar of petals that can be a different color. Colors include yellow, orange, white, red, and peach.
