ANNUAL Happy Days® Yellow Dahlia

Dahlia Happy Days Yellow ®is a cheerful, compact dahlia that produces vibrant golden-yellow blooms from late spring through frost. Its bright single flowers stand out beautifully against deep bronze-purple foliage, creating striking contrast in garden beds, patio containers, and mixed borders. The open-centered blooms are highly attractive to butterflies, bees, and other pollinators, bringing movement and life to the garden all season long.

This tidy, bushy variety grows approximately 18–24 inches tall and wide, making it perfect for containers, edging, and smaller garden spaces. Happy Days Yellow® thrives in full sun and well-drained soil, performing best with regular watering and occasional deadheading to encourage nonstop flowering. Heat tolerant and easy to grow, this dahlia delivers bold color and dramatic foliage throughout the summer months. Hardy in USDA Zones 8–11 and commonly grown as an annual in cooler climates.
