Noteworthy CharacteristicsMay be hardier than some other glads. Slightly looser, more casual habit.

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.
