When to plant Calla Lily
Plant calla lily rhizomes once the weather has warmed up in spring and the threat of frost has passed (NC State). Calla is hardy to about zone 8; in zone 7 it can survive with protection, and in colder areas it is overwintered indoors or grown as an annual.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
