Notes
Oneleaf onion (Allium unifolium) is a bulb for borders and low maintenance gardens. It is typically grown as an annual. It ranks among the more cold-hardy crops, and with some winter protection it keeps growing through light freezes. This plant likes full sun to part shade and average to moist soil of most types. It sits low on the menu for deer and rabbits. The fragrant white or pink flowers attract bees and butterflies.
Pairs well with Lemon balm, Holy basil, and Gentian.
