Planting & Growing
Spring Onion will grow to be about 14 inches tall at maturity extending to 30 inches tall with the flowers, with a spread of 18 inches. When planted in rows, individual plants should be spaced approximately 14 inches apart. This fast-growing vegetable plant will behave as an annual in our climate, which means that it can be expected to grow for one season in your garden and then die after producing a crop. As this plant tends to go dormant in summer, it is best interplanted with late-season bloomers to hide the dying foliage.
This plant can be integrated into a landscape or flower garden by creative gardeners, but is usually grown in a designated edibles garden. It does best in full sun to partial shade. It does best in average to evenly moist conditions, but will not tolerate standing water. It is not particular as to soil type or pH. It is highly tolerant of urban pollution and will even thrive in inner city environments. This species is not originally from North America. It can be propagated by division.
