Planting Instructions
Hyacinths need at least a half day of sun to flower well and store up enough energy for the following spring’s display. They grow in any well-drained soil. The flower heads are at their largest and fullest the first spring after planting; in subsequent years the flowers tend to be more loose and informal.
Note: Hyacinth bulbs can irritate your skin. Wear gloves when handling and plan on showering soon after planting.
