Dividing the clump is the classic method for propagating calla lilies. Another propagation method is by seed.
Like any seed, it needs to mature before being collected. Harvesting too early is bound to fail. Therefore, it’s important to keep the calyx on the floral spike for as long as possible. Nature is wise, as the flower matures, the stem bends its head to keep the seeds dry. It’s not necessary to stake it.
Good to know:
The flower is fertilized in water.
The seeds grow inside the very humid calyx.
When and how to collect calla lily seeds?
The initially green seeds turn dark brown, passing through orange-yellow depending on the varieties.
Seed collection should be done with gloves, as the plant is toxic, just like its cousin, the spotted calla lily or Moses’ cradle.
Storing Ethiopia calla lily seeds
Allow the seeds to dry on absorbent paper in a dry place (basement, garage, garden shed), out of reach of children.
Place the seeds in a bag.
Store the seeds in a dry place protected from light (old refrigerator).
Keep the seeds in a cool place for at least a week before sowing them in March-April (or even earlier) with warmth, in a seed starting mix.
