One of the loveliest Sword-Lily, Gladiolus 'Atom' features unbelievably beautiful bright red petals delicately edged with a silvery white lining. Highly popular since its introduction in 1946, its long-lasting and eye-catching flowers (up to 7 per stem) grow on loose spikes (2-3 spikes per corm) that are adorned with narrow, deep-green sword-shaped leaves. Since the flowers open from the bottom of the spike up, sword-lilies provide a long-lasting floral display, each flowering spike blooming for up to two weeks. Spectacular on its own, in the garden or in a vase!
