To reduce exposure, keep the plant in well-ventilated areas and avoid touching flowers if you are sensitive.

Notes
Prune dead flower stalks to encourage new blooms. In colder climates, dig up rhizomes before frost and store them indoors. Repotting is generally needed every few years if grown in containers.
