Grape Hyacinth
Muscari armeniacum
Family Asparagaceae

A river of electric blue for pocket change — that's the grape hyacinth trade. Each bulb sends up a little spire of tight cobalt beads in spring, and a hundred of them scattered under trees and along paths read as one brushstroke of pure color exactly when the garden needs it.
Early bees work the flowers hard when little else is open. At six to eight inches it tucks under anything, naturalizes into bigger drifts each year, and asks for nothing after planting — though the bulbs are mildly toxic to pets, so bury them where dogs don't dig. Scatter a bag and wait.
