Often grown as an ornamental plant in gardens, several cultivars are available. A. tuberosum is distinctive by blooming later than most native or naturalised species of Allium.[15] It is cold-hardy to USDA zones 4–10 (−30 to +35 °F, −34 to 2 °C).[8] Garlic chives are regarded as easy to grow in many conditions and may spread readily by seeds or can be intentionally propagated by dividing their clumps.[19]
