Eiffel produces an upright growing, white Lisbon type scallion with little or no bulbing at the root end, even in the heat of summer. This variety grows straight, with mild, appealing flavour and good uniformity. Its stiff upright leaves shed the rain, so it is less susceptible to the diseases that can occur in damp weather. Sow short rows of Eiffel scallion seeds every two weeks from April to the end of September, and you'll have scallions all year long. Provide a cloche row cover over winter for the best results.
