Gladiolus

Gladiolus 'Atom'

glad-ee-OH-lus Audio

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.

    You don't have to dig this up unless you are north of zone 6 - maybe even 5b if you put it in the right microzone.
