I am a landscape designer and have been purchasing 1000's of spring flowering bulbs from A.D.R. Bulbs for 100's of clients in the last 20 years. The bulbs have always been of top quality and if there were any problems, they have been quick to rectify. My orders are often complicated with many varieties and different amounts and they have always filled and delivered everything on time with the best customer care and attention to detail. The pictures in their catalog and website are beautiful. I have visited their facility in NY and was impressed with all their handling equipment and organization. I would highly recommend A.D.R. Bulbs to anyone in the wholesale trade who wants to purchase quality bulbs and work with genuinely nice people.

Muscari 'Latifolium'

Grape Hyacinth

Muscari latifolium, commonly known as Broad-leaved Grape Hyacinth, is a bulbous perennial that reaches 6 to 16 inches in height. It produces bicolor flower spikes, with deep violet-blue fertile flowers at the base and soft lilac sterile flowers at the top, creating a striking contrast.

Thriving in full sun to part shade, Muscari latifolium prefers well-drained soil and naturalizes well, forming dense drifts over time. It is deer-resistant, drought-tolerant, and mildly fragrant, making it an excellent choice for borders, rock gardens, and woodland edges.

Growing and Maintenance Tips for Muscari 'Latifolium'

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.
