The resplendent Easter lily is well known for its white trumpet-shaped blossoms. Easter lilies are often grown in pots and forced for a March bloom, but they are also grown outdoors and bloom naturally in summer. They produce a seed pod inside each flower. These seeds can be harvested and sowed indoors in early spring, to be transplanted outdoors after the last frost.
Allow the seed pods to dry on the plant. If there is a danger of frost, bring the plants inside for the pods to finish drying.
Cut the dried pod off of the stem. A dry pod is brown; an immature pod is still green.
Break open the pod to collect the seeds. Use a spoon to carefully scrape the seeds from the pod if necessary.
Plant the seeds the following spring. Easter lily seeds lose their vigour within several months stored at room temperature. If you plan to store the seeds, keep them in an airtight container in the freezer to extend their viability for a few years.
