Grape Hyacinth
Muscari armeniacum
Family Asparagaceae
Est. zones 4-8
The little bulb that plants rivers of electric blue in spring for pennies — buy 100, scatter them under trees and along paths, and they naturalize into drifts. Early bees adore them. One quirk that alarms beginners: the grassy leaves sprout in fall and sit all winter before the spring flowers; that's completely normal.
