Birds of paradise flowers are easily recognized by their unique shape, which resembles a bird flying through the air. Each stem is capable of growing to the height of an average human and producing multiple flowers. Each flower contains a seed pod that holds hundreds of tiny black seeds. The pods make harvesting the seeds a quick and easy task.
Wait for the seed pods to mature. This occurs after the flowers bloom and begin to die off. The pods are easily distinguishable from the rest of the flower, as they are tan colored and full of tiny black seeds.
Snap the pods off of the flower with your hands. Be gentle when handling the flowers to avoid damage to the plant.
Hold the pod over a bowl and break it open. The seeds will immediately fall out of the pod. Remove any pod residue from the bowl and discard it.
Pour the seeds into a paper envelope. Store the envelope in a cool, dry place until you are ready to use them.
