Description
The best Allium we’ve grown so far in our own gardens. Millenium Allium features abundant, fragrant and perfectly shaped globes of rosy pinkish purple flower clusters from early summer to late summer, depending on your location. Either way, this one blooms much later than other alliums, which bloom in spring. The pretty flower globes are perched on strong stems so that they sit just atop the upright clumps of attractive, glossy green leaves. Both the leaves and flowers of Millenium Allium have a sweet fragrance. Combining interesting flower shapes creates a garden with texture and depth, this little ornamental onion hybrid has it all – long-lasting blooms, fragrance and nice foliage on a low-maintenance and drought-tolerant plant!
Landscape & Garden Uses
Growing to 15-20 inches tall and 10 to 15 inches wide, Alliums are ideal for use as an accent, in groupings or mass plantings in perennial borders and herb gardens. Just make sure to deadhead spent flowers if self-seeding is not desired. Also well-suited for growing in container gardens, which can be overwintered indoors above Zone 4a. A fine selection for herb gardens, perennial gardens, purple theme gardens, cottage gardens, butterfly gardens and rock gardens.
Note: For our customers who live and garden north of USDA Plant Hardiness Zone 4a, where Allium are not winter hardy, you’ll be happy to know it can be grown in containers that can be brought indoors during winter and placed back outside when temperatures warm up in spring.
Growing Preferences
Allium are very easy to grow in most any moist but well drained soil of average fertility. Not picky at all about soil pH. grows well in full sun to part shade. We suggest at least 4 hours of sun per day for best growth and flowering. Remove spent flower heads if self-seeding is not desired. The leaves are best harvested by clipping them off at the base in order to maintain attractive appearance..
Plant Long & Prosper!
