Alliums are often popularly used as ornamental plants due to the showy, colorful blooms produced by many allium species. However, considering that the number of known allium plant species exceeds 500, it is not surprising to learn that not all allium plants make a welcome addition to the garden. Alliums like wild garlic, wild allium, and three-cornered leek can very quickly turn invasive and overtake the entire growing area. These pesky weeds are persistent, but not undefeatable. Digging, pulling, mowing, and carefully applied herbicides all can be used to try and control invasive alliums and prevent their spread.
- A number of species of alliums produce dazzling, colorful blooms, which make them a favorite in many different gardens
- Some species of alliums, like wild allium and wild garlic, are invasive and can rapidly take over a garden at the expense of other plants
- Some effective ways to combat an allium invasion in your garden include regular mowing, pulling the plants out by the root, digging them out, and targeted application of herbicides to kill them
“Allium, known for its pungent aroma, includes more than 500 species, including the familiar onion, garlic, chives and a variety of beautiful flowering plants. Pollinators love the hardy, long-lasting plants, but deer and other critters usually leave them alone.”
