Take one look at an Allium Millenium in full bloom, and itâ€™s no wonder this stunning plant was selected the 2018 Perennial Plant of the Year by the Perennial Plant Association. The globe-shaped lavender flower heads, arising by the dozen, last for a month or more. Millenium is a splendid late-summer bloomer, ready to deliver outstanding garden color just when many flowering plants are giving up their show for the season.
The flower heads are perfectly round and reach about 2 inches in diameter, studded on all sides with purple florets tinged with red. Like all Allium, the plant has a scent (itâ€™s an onion, after all), which keeps away nibbling rabbits, deer and other hungry creatures. On the other hand, butterflies and bees find the blooms enticing.
This ornamental onion reaches about a foot high and wide, with a dense bouquet of dark green stems topped by bobbing blooms. Unlike older varieties, it wonâ€™t scatter seed all over the garden. Instead, it concentrates all its energy on setting flowers, and the results are magnificent. Just give it plenty of sunshine, well-drained soil on the light side, and wait for the flowers.
