Grape Hyacinth has masses of beautiful spikes of blue bell-shaped flowers rising above the foliage in mid spring, which are most effective when planted in groupings. Its grassy leaves remain green in color throughout the season.
Grape Hyacinth is an herbaceous perennial with an upright spreading habit of growth. Its relatively fine texture sets it apart from other garden plants with less refined foliage.
Grape Hyacinth will grow to be only 4 inches tall at maturity extending to 8 inches tall with the flowers, with a spread of 4 inches. It grows at a medium rate, and under ideal conditions can be expected to live for approximately 5 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen! As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.
This plant should only be grown in full sunlight. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by multiplication of the underground bulbs.
