Dutch hyacinth is a spring bloomer with foot-tall spikes densely packed with waxy, bell-like, fragrant flowers in shades of blue, purple, red, pink, buff, and white.
It grows best in cold-winter areas, where it lasts from year to year; in these zones, plant in September or October. In mild areas, bulbs will not persist and are best treated as annuals; plant from October to December. Set bulbs 4 to 5 inches deep, 4 to 5 inches apart.
