Green Onions
Green onions (Allium fistulosum), also called scallions, hail from Asia and are a delight for bucket gardening year-round. Their shallow root systems make them perfect for a five-gallon bucket filled with loose, fertile soil. I plant my green onions at eight-week intervals, which ensures a continuous supply of crisp, mild-flavored stalks. Throughout winter, buckets placed on a sheltered porch stay just warm enough to keep these hardy onions growing slowly, offering fresh sprouts even when snow is on the ground.
Though perennial green onions can naturalize in mild climates, they rarely become invasive in containers. Plus, their onion-scented foliage acts as a deterrent to small pests like aphids and carrot rust flies—especially appreciated if you have a carrot bucket nearby! On sunny days, bumblebees sometimes inspect the tiny, globe-shaped blossoms if any bulbs bolt to seed, creating small nesting pockets under adjacent straw mulch. Those same blossoms attract beneficial hoverflies whose larvae feast on nuisance aphids. Whether you’re stirring scallion greens into stir-fries or tucking them into winter soups, green onions make a fuss-free nibble or garnish well beyond the typical garden row.
