I have worked with A.D.R. Bulbs for almost 5 years now, and my company has sourced bulbs with them for longer than that. Communication is great - from ordering, to deliveries, to follow-ups on final product. I love the quality of the product as well as the service. We plant nearly 100,000 bulbs and A.D.R. keeps the whole process easy for us!

Muscari 'Armeniacum'

Grape Hyacinth

Muscari armeniacum, commonly known as grape hyacinth, is a bulbous perennial that grows 6 to 8 inches tall. It produces dense clusters of cobalt-blue, bell-shaped flowers, each rimmed with white, blooming in mid- to late spring.

Thriving in full sun to partial shade and preferring well-drained soil, this species is deer-resistant, drought-tolerant, and mildly fragrant. Its adaptability makes it a standout choice for borders, rock gardens, containers, and naturalized plantings. It remains the most popular variety of Muscari by far.

Growing and Maintenance Tips for Muscari 'Armeniacum'

Planting: Plant bulbs in fall, 3 to 4 inches deep and 2 to 3 inches apart, with the pointed end up. For a natural look, scatter and plant where they fall.
Location: Full sun to partial shade. Ideal under deciduous trees where spring light is abundant before leaf-out.
Soil: Well-drained, moderately fertile soil with a neutral to slightly acidic pH (6.0–7.0). Tolerates sandy or loamy soils.
Watering: Water after planting and during active growth in spring. Once foliage yellows, reduce watering—bulbs prefer dry summer dormancy.
Temperature: Hardy in USDA zones 4–8. Requires a cold period to bloom reliably.
Fertilization: Apply compost or a low-nitrogen fertilizer in fall or early spring. Bone meal is also beneficial at planting.
Pruning: Allow foliage to die back naturally—it nourishes the bulb for next year. Remove seed pods if you want to limit self-seeding.
Propagation: Naturalizes easily by offsets and self-seeding. Divide clumps in summer when dormant if needed.
Pest & Disease: Generally pest-free. Deer- and rodent-resistant. Good drainage prevents bulb rot.
