Dutch hyacinth is a fragrance powerhouse in the garden. Its stocky blooms open in midspring, around the time that daffodils strut their stuff. The blooms release a rich, full fragrance that can fill the spring garden. Indoors, pots of forced hyacinths bring spring scents to life in the heart of winter. Plant bulbs in fall for a spring show in the garden. Choose flower colors in many shades, including pink, purple, blue, salmon, white and red. Hardy in Zones 4-8.
