When to Plant
Delivery & Planting Times
Spring-flowering bulbs must be planted in the fall. They need cool soil to make roots before the onset of winter. Cool fall weather arrives at different times from north to south and from high elevations to low.
Please note that the temperature of the soil lags behind the air temperature. You can generally plant later than the windows provided in this map. As long as the ground is not frozen, you can still plant.
Dense, relatively compact heads of what might best be called a soft lavender-blue. If that sounds indecisive, it’s because the color you perceive will depend heavily on the light: Early and late in the day, you will likely see purple; in shade or under high clouds, the blue will come through. And the fragrance? It is strong and sweet all day, every day.

Bulb size is determined by the circumference around the largest part of the bulb. Colorblends only delivers top size bulbs. Large bulbs produce more or larger flowers than small bulbs.
Hardy in USDA zones 4a to 8b in the South or 10b on the West Coast. Prechill in zones 7b and warmer in the South, Southwest, and California.
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.
