Calla lilies typically bloom starting in late spring to early summer , depending on the climate. In warmer climates, they can begin blooming in late spring, with bloom times lasting up to 8 weeks through the summer. In most regions, you can expect calla lilies to flower sometime from May through July. Specifically:
- Calla lilies planted outdoors after the last frost and when soil temperatures reach around 60-65°F will usually bloom 2 to 3 months after planting , often resulting in blooming around May to July depending on the planting date.
- In colder zones, calla lilies are often planted in spring after danger of frost has passed and tend to bloom in early to late summer.
- The flowers last for several weeks, often between 6 to 12 weeks depending on variety and conditions.
- Indoor potted calla lilies can also bloom and will last for several months if well cared for.
To encourage earlier blooming, calla lilies can be started indoors in pots before transplanting outside, which can advance the blooming by one to two months compared to directly planting outdoors. In summary, calla lilies bloom in late spring through summer, typically from May to July, with variations based on planting timing and climate conditions.
