How to grow calla lily
Zantedeschia aethiopica
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.
Calla Lily is timed by season rather than your frost dates, so the planting calendar does not generate ZIP-specific dates for it. Check the cited sources below to fine-tune for your area.
