Grape Hyacinth

Grape hyacinths produce several dense spikes of tiny, true blue flowers from each bulb. They are beautiful on their own, but their greatest value may be as companions to midseason tulips. That rich blue makes almost any tulip color pop.

Bloom times are relative within the spring bulb season, which varies from place to place and year to year. They are intended to help you plan a sequence of bloom from Very Early season to Very Late season. About two weeks separate Early from Mid and Mid from Late. The start and duration of bloom is heavily dependent on the weather. Warm temperatures speed up growth and flowering; cold temperatures slow them down.

Planting Instructions

These bulbs thrive in full sun or partial shade and any well-drained soil. Muscari armeniacum bulbs planted in a prior year often produce tufts of grasslike foliage in fall, which has the benefit of reminding you where they are when you are planting additional bulbs. They will bloom on schedule the following spring.

Note: Do not be concerned if you see blue mold on your muscari bulbs. Go ahead and plant them. The mold will not affect their performance.


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.

The amaryllis are the last bulbs to arrive in the Colorblends warehouse. They are typically available for delivery toward the end of October. They can be planted upon receipt. They can also be stored in a cool, dry location for several weeks. Please note: Amaryllis bulbs may start growing before they are potted. If you decide to delay planting, open the bag(s) and set the bulbs on their roots so that the flower stems can grow straight up. And don't forget to mark your calendar or set a reminder to pot the bulbs.
Paperwhites can be potted upon receipt. They can also be stored in a cool, dry location for many weeks. Many people pot their bulbs in batches, one after the next, to keep the fragrance coming. It's not unusual for paperwhites to begin to sprout while in storage. The shoots emerge an inch or two and then stop, as though the bulbs realize they are getting ahead of themselves. The shoots often curl around the bulbs, pointing opposite gravity. After the bulbs are potted, the shoots straighten up.
