Bloom Time Mid
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 late summer or early 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.
