Probably the best of the large headed Alliums a hybrid of Allium cristophii and Allium macleanii. Exceptionally long lasting flowers - the first array is replaced by another second flush of their deep violet-purple blooms. The insects still love to feed on them, although despite their attentions you’ll not be left with a remnant seed head as they are sterile. Tidier leaved than most, even at flowering time. Plant them about 12” (45cm) apart in well drained soils in good light. Great planted with Astrantia ‘Roma’.
Allium Globemaster has been awarded the RHS Award of Garden Merit because it has proved to be reliable in appropriate conditions and a good performing plant.
Plant the Allium Globemaster bulbs in a sunny situation in good, fertile, well drained soil, about 5-6" (12-15cm) deep and 18" (45cm) or more apart.
