Alliums are a genus of flowering plants in the onion family. They are known for their distinctive, spherical blooms that come in a variety of colors, including purple, pink, white, and yellow. Some common varieties of Alliums used in landscaping include Allium giganteum (giant onion), Allium moly (yellow onion), and Allium 'Globemaster' (a large purple variety). Alliums are easy to grow and care for, and they are drought-tolerant and resistant to pests and diseases. They are also deer-resistant, making them a good choice for landscaping in areas where deer are a problem. Alliums can be planted in a variety of soils, but they prefer well-drained soil and full sun. They are also well-suited for rock gardens, cottage gardens, and mixed borders.
