Planting & Growing
Blue Spike 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 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 is a selected variety of a species not originally from North America. It can be propagated by multiplication of the underground bulbs; however, as a cultivated variety, be aware that it may be subject to certain restrictions or prohibitions on propagation.
