Those bulbs you just bought at the Show are special prepared for planting in containers.
After done blooming the plants can be planted in the gardens. Or can be planted direct in the gardens direct.
Easily grown in rich, sandy to gritty, dry to medium moisture, well-drained loams in full sun. Plants form dense, slowly-spreading clumps over time. They perform best in dry, sunny areas of the garden. Established plantings have good drought tolerance. Best sited in areas protected from strong winds. Plant new bulbs 4-6" deep (3 times bulb diameter) and 12" apart in fall. Bulbs of established plants may be dug, divided and replanted in late summer to early fall after foliage has died down. 'Globemaster' is a sterile hybrid that does not produce seed, so self-seeding is obviously not a concern.
Ornamental onion for rock gardens, beds and borders, cottage gardens and meadows. Best planted in large groups or massed. Excellent in containers. Cut flowers are excellent for both fresh cut and dried flower arrangements.
