Allium altissimum Goliath Bulb

Allium altissimum 'Goliath' is a majestic ornamental allium cultivar renowned for its impressive, large globular flower heads composed of tiny star-shaped florets in pale lilac to soft purple hues. Blooming in late spring to early summer, the striking spherical blooms rise on exceptionally tall, strong stems, making it a dramatic architectural feature in large borders, cottage gardens, and mixed perennial plantings. This cultivar thrives in full sun with well-drained soil and prefers a sheltered location to encourage sturdy growth and prolonged flowering. Once established, 'Goliath' is drought tolerant and requires low maintenance, ideal for gardeners looking to create impactful displays with minimal effort. Its nectar-rich flowers attract pollinators such as bees and butterflies, supporting biodiversity. Not native to the UK, it remains a popular choice for adding vertical interest and bold colour to temperate gardens.
