Plant Profile: Allium aflatunense

The Ornamental Onion is a flowering bulb native to central Asia, known for its vibrant blooms that appear in May and typically last for 2 to 3 weeks. This plant can reach heights of 24 to 36 inches, showcasing large, rounded clusters of flowers atop tall, leafless stems. It flowers after daffodils and tulips have finished blooming, but before perennials begin to emerge. Characterized by a distinct onion or garlic scent, it also serves as an excellent cut flower.

For optimal growth, plant the bulbs 4 to 6 inches deep and spaced 4 to 6 inches apart in well-drained soil, ideally in full sun to partial shade during the fall for spring flowering. These bulbs are versatile and can be used in rock gardens, flower borders, or naturalized areas, whether in small or large groupings. While they are drought-resistant in the summer, they benefit from some moisture during their blooming period.
