After the calla lily blooms, the flower pod seems to produce what looks like a cluster of small bulbs. Is this a seed pod?
Calla lily seed pod
When the flower is fertilized it will produce a green cluster of kernels resembling a pineapple. As the seed pod matures, it will turn yellow and become soft and mushy. This can take several months and is usually ready in the fall. If you pick it before it matures, the seeds will not be viable.
Harvesting the seed
You can remove the seeds by pinching or squishing each berry between your fingers which can hold 1-5 sticky seeds. Rinse the pulpy residue on the seeds. At this point you can either plant the seeds in moistened potting soil or store them in the refrigerator until you are ready to plant.
Another way is to let the whole “seed pod” dry until it turns a orange, gold color. Clean off the fleshy coating and take out the seeds. Store the seeds in a cool, dry place (frig) until you are ready to plant.
How to plant calla lily seeds
Push the seeds into well-drained soil 1/4″-1/2″ deep and 1/2″ apart. Keep the soil moist at a temperature of 70-80 degrees. Germination can take 30-90 days. Transplant seedlings when after they have developed 2-3 leaves.
To check for seed viability, place seeds between moist paper towels for 2-3 days.
When starting Calla lily from seeds, you never know what you’re going to get. The new plants will most likely not resemble the parent plant but you may be surprised with a new cultivar.
