I have made several vidoes on cala Lilies. Varigated and Non-varigated Calla Lilies. How to care for the seeds that Calla Lilies produce while on the plant and how to store them for next year. We live in zone 7 and they should be pulled before winter. We have had mild winters for the last several years and have left ours in the ground. Calla’s take 3 to 4 years to flower from seed, but with the varigated kind you still have the beautiful foilage. You can also divide the bulbs and plant them eyes up smooth side down. They like morning sun and afternoon shade. Any well balanced fertilizer will do.They do not like wet feet and they do not like to dry out. The flowers last about three weeks.
