A glad for people who would normally never grow them, 'Atom' is about half the size of regular varieties, growing to at most 3 feet tall. This 1946 classic blends easily into perennial borders, and it won't get lost because its flowers are blazing red cooled by a thin, silvery edge.
Noteworthy CharacteristicsShorter stature than most glads, with an eye-catching flower color that nevertheless fits well into borders.
CareFull sun to part shade in fertile, well-drained soil. Treat as annuals, or dig up and store 6 weeks after bloom (dip in fungicide and allow to dry for a few weeks).
PropagationSow seed at 59°F in spring. Separate cormlets when dormant.
ProblemsGladiolus corm rot (Fusarium), gray mold (Botrytis), viruses, aster yellows, spider mites, thrips, aphids.
