Overview
Grape hyacinth (Muscari armeniacum) is a mid-spring blooming, perennial bulb in the asparagus family (Asparagaceae) native to southeastern Europe. It is not a true hyacinth (genus Hyacinthus). The genus name, Muscari, derives from the Greek “musk,” in reference to the strong scent of the flowers of many species in this genus. The common name comes from the resemblance of the clusters of the small, bell-shaped, cobalt-blue flowers to clusters of grapes. Grape hyacinth is hardy in zones 4a to 9b.
Long, linear, floppy, green leaves emerge from the ground in early spring and are soon followed by the flowers. The foliage dies back after in early summer after flowers fade, but unlike many other spring-blooming bulbs, it starts growing actively again in mid-fall and persists through mild winters.
Each bulb produces one to three 4 to 8 inch high flower stalks with 20 to 40 tightly packed flowers per stalk. Each bell-shaped floret has a thin white band on the rim. Most have a mildly sweet fragrance variously described as slightly grassy or grapey. They are excellent as cut flowers and can be used for indoor forcing. The flowers open sequentially from the bottom up the inflorescence, with the lowest flowers withering as the top ones open. Pollinated flowers are followed by tripartite seed pods. They readily naturalize, reproducing by division and self-seeding, sometimes aggressively in some situations.
Landscape Use of Grape Hyacinth
Grape hyacinths are good for planting in rock gardens, in the front of beds and borders, and along walkways and paths. They mix well with other early blooming bulbs, and are a popular container plant. They look best in masses and loose drifts and are particularly nice when allowed to naturalize under trees and shrubs.
There is a famous planting of grape hyacinth at Keukenhof Gardens in The Netherlands known as the Blue River. This dense planting of M. armeniacum winds past trees, shrubs, and other spring flowers, giving the illusion of a flowing blue river. You can try planting a large drift of grape hyacinth in your garden for a similar effect – but this takes a lot of bulbs!
Grow grape hyacinth in well-drained soil in sun to shade. Place in full sun for maximum vigor. However, the flowers last longer in partial shade.
Plant Grape Hyacinth bulbs in the fall, placing bulbs 3 to 4 inches deep and 2 inches apart. The plants benefit from fertilization after blooming. Reduce watering after the foliage begins to die back.
Cultivars of Grape Hyacinth
There are several varieties of this M. armeniacum, as well as some related species and cultivars.
- ‘Alaska’ has pale blue flowers with white edging.
- ‘Album’ is a fragrant, white-flowered selection that is not as vigorous as the standard type.
- ‘Cantab’ has sky blue flowers and blooms slightly later than the standard type. It grows 6 to 8 inches tall and 4 to 6 inches wide.
- ‘Fantasy Creation’ has double blue flowers that may develop green overtones as they age.
- ‘Julia’ has stems with medium blue flower at the base and pure white at the top, providing a bicolor effect.
- ‘Mountain Lady’ grows 6 inches tall with racemes of perwinkle blue flowers with white edges, topped with pure white florets.
- ‘Pink Sunrise’ features 6 inch tall spikes of pale pink flowers topped with white florets.
- ‘Saffier’ has deep blue flowers that are longer lasting than most varieties because they have small openings and are difficult to pollinate.
- ‘Siberian Tiger’ has dense flower spikes of pure white flowers and grows 8 to 10 inches tall.
There are about 40 species of Muscari, and some of the more commonly available are listed here.
- M. aucheri is native to Turkey and features flower spikes with blue lower flowers and lighter blue flowers atop the spike. Zone 4a hardy. ‘Blue Magic’ has sky blue top florets and sky blue lower florets and grows 6 to 8 inches tall. ‘Dark Eyes’ spikes have dark blue flower florets with white rims and lighter blue florets at the top. ‘Ocean Magic’ flower spikes have dark blue lower florets, pale blue central florets, and white florets on top.
- M. azureum has bright blue flowers that open more widely than M. armeniacum. It grwos 4 to 6 inch tall and blooms in early spring. The variety M. azureum var. alba has white flowers.
- M. botryoides, called compact grape hyacinth, grows 4 to 6 inches tall and 2 to 6 inches wide, with bright blue lower flowers and white flowers atop the spikes. Zone 4a hardy.
- M. comosum, or tassel hyacinth, blooms in late spring, with purplish brown flowers on 8 to 12 inches plants hardy to zone 4a. Variety ‘Plumosum’ (feather hyacinth) grows 6 to 8 inches tall, with threadlike, sterile, purple-blue flowers that create the appearance of a feathery plume and is zone 5a hardy.
- M. latifolium is native to pine forests in Turkey and produces a single leaf from each bulb. It blooms in early spring with bicolor flower spikes that have pale blue florets on top and dark blue-black on the bottom. The 6 to 12 inch tall plants are hardy to zone 4a. ‘Grape Ice’ has dark purple flowers at the base and pure white flowers at the top. It grows 6 inches tall.
