Garden Grape-hyacinth (Muscari armeniacum) — identification, habitat & look-alikes

Garden grape-hyacinth is a spring-flowering bulb grown in U.S. gardens, with tightly packed blue, bell-shaped flowers. Its bulbs multiply and can spread beyond a planting bed. It is often called simply grape hyacinth.

Appearance

Appearance: A small bulb 6–9 in (15–23 cm) tall. Narrow, grassy leaves come up in fall and last through winter into spring.
Flowers: Tiny bell-shaped flowers pack the top of each stem like an upside-down bunch of grapes. They are deep violet-blue with a thin white rim; some selections are mildly fragrant.
Flowering time: In North Carolina, it blooms in April and May.

Look-alikes

Common grape-hyacinthMuscari botryoides

The two can be nearly identical in flower photos. Common grape-hyacinth has leaves that widen near their rounded, hooded tips; garden grape-hyacinth leaves stay narrow to the tip. A photo showing leaves helps.

Starch grape-hyacinthMuscari neglectum

Starch grape-hyacinth often has nearly black-purple lower flowers and paler flowers above. Garden grape-hyacinth is usually a more even blue, but color alone may not settle a photo.
