It is not recommended to collect Plumeria seeds from unripe seedpods. Seeds harvested from unripe seedpods are often immature and may not be fully developed or viable for propagation. For successful germination and growth, it is essential to wait until the seedpod reaches full maturity before collecting the seeds. Unripe seeds have a lower chance of germinating and establishing healthy plants. Therefore, it is best to be patient and allow the seedpod to fully ripen before harvesting the seeds for planting or storage.
