Millenium Ornamental Onion

‘Windy City’ Ornamental Onion (Allium giganteum) is a striking perennial that stands tall with its impressive globe-shaped clusters of violet-purple flowers, creating a dramatic focal point in any garden. Thriving in full sun and well-drained soil, this hardy variety is perfect for borders, cutting gardens, or mixed beds. Blooming in late spring to early summer, its unique flowers attract pollinators while adding vibrant color to your landscape. To enhance its performance, ensure proper spacing for airflow and cut back the foliage after it has faded to promote healthy growth for next season’s blooms.
