The biggest & the best.. . Allium Globemaster is a fantastic plant with enormous, deep-magenta flower heads that grow up to 20cm (8in) across, bursting with vibrant colour from May into June each year. Growing to 1m (3ft) tall, each of these bulbs will look great in pots or borders & will thrive & form a multi-stemmed clump in any garden. Coming back year after year with bigger & better flowers, the stems last really well once dried too.
