Hyacinths are among my favorite spring bulbs. They generally perform as well as daffodils do here. I force a few to give away and plant the rest directly in the ground after chilling for 12 weeks.
Many bloggers show their beginning bulbs planted in soil, or in vase with water. Once the forced bulbs are done, most toss the spent bulb. I advocate saving the bulb to plant in the garden as soon as possible.
